[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-07-02 Thread Alejandro Mery
and btw, installing backport-iwlwifi-dkms doesn't fix it either.
it's hard to digest one need to manually upgrade the kernel when using the 
latest LTS or a known (and fixed upstream) bug on a very popular wifi driver 
will take your whole USB bus out of service

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-06-27 Thread Sairam D
This issue is fixed with kernel version 5.4.49 (current longterm
kernel). I was having the exact same issue for almost 3 months. My Wifi
speed used to get throttled whenever I download something or just
consume more bandwidth continuously. More importantly whenever the
throttling happens, the laptop also freezes for a few seconds. During
these 3 months I tried several iwlwifi configurations, changed its
driver versions... etc. Nothing worked.

But then updating the kernel from version 5.3.0 to 5.4.49 manually fixed
the issue. Now the wifi works perfectly without any issues. I haven't
faced any other issue with this kernel yet(I am on Ubuntu 18.04). Also,
now I couldn't see any iwlwifi error messages getting reported in dmesg
logs.

2020-06-21 Thread Emma Aioi
Update: changing kernel to 5.4.8 fixes the issue for anyone here looking
for a fix, but do so at your own risk. The latency is super high and the
speeds are abysmal for me, so it's still a big problem, but it becomes
usable at this point.

2020-06-20 Thread Emma Aioi
Having this problem on my newly installed Ubuntu 20.04 system. Tried using the 
11n_disable=1
workaround, didn't work.
modinfo output:

$ modinfo iwlwifi | grep 9260
firmware:   iwlwifi-9260-th-b0-jf-b0-46.ucode

Turning networking off and back on resets the issue, but after about
half a minute, it crashes again under load.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-06-16 Thread otheos
Yes, I think it is related to dual booting and the source of the problem
might be indeed in the Windows driver leaving a setting on the card that
the fw and driver in linux cannot cope with. Rebooting to linux from
Windows causes a lot of trouble, but rebooting from linux to linux
solves it. (Maybe after a couple of reboots until the card resets -no
idea how this works).

Status in linux package in Ubuntu:

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

I don't seem to have this problem on Ubuntu 18.04, 5.4.0-37 hwe-edge
kernel. I don't seem to have this problem on Ubuntu 20.04 live session
either. At least. speedtest can't reproduce the issue. Even tried
rebooting from Windows. Those who have the problem and dual boot, could
you try upgrading your Windows driver to latest and see if it helps? I
once had a RTL Ethernet card issue on Linux and it ended up getting
fixed by upgrading driver on Windows.

I second that. Neither the -34 nor the -43 version fully resolve the
issue. 5GHz WiFi is practically unusable. 2.4GHz mostly works with -34
and -43, but keeps disconnecting. It's not really usable.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-06-11 Thread Massimiliano Mantione
One more report.

Kernel 5.4.0-33-generic with the older
"iwlwifi-9260-th-b0-jf-b0-34.ucode" firmware is not working flawlessly:
it periodically disconnects starting with an error "iwlwifi
:05:00.0: Error sending ADD_STA: time out after 2000ms.".

Probably once per hour.
Perhaps it happens because I had to reboot into Windows this morning...

Anyway, this bug is definitely still unfixed :-/
And consider that Fedora on 5.6 is in the same boat.

  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-06-06 Thread Massimiliano Mantione
I am on 20.04, kernel "5.4.0-33-generic".
I also see this problem.
The easiest way to trigger it is to run an ADSL speed test, then the system 
freezes at random for several seconds and the iwlwifi log messages are the same 
as the initial bug report.

I had the problem in the past on 19.10, kept it at bay sticking to a 5.0
kernel kept from a 19.04 install.

After months the problem went away, it's not clear with which kernel. I
just booted on a new kernel by mistake and the system worked properly.

A few days ago the problem resurfaced on 19.10, and my old 5.0 kernel was not 
working anymore.
Sometimes I stay weeks or months without rebooting...

I tried upgrading to 20.04 but it did not help.

I tried fresh installs of Fedora 32 and Ubuntu 20.04, and in both cases the 
live boot did not have the issue but the system after install did, but *mostly* 
after enabling Nvidia drivers.
My problem is that I need CUDA so Nvidia drivers are a must for me.

What is working now is symlinking "iwlwifi-9260-th-b0-jf-b0-46.ucode" to
"iwlwifi-9260-th-b0-jf-b0-34.ucode" as described in a previous comment.

I did not even have to download "iwlwifi-9260-th-b0-jf-b0-34.ucode", I
already had it in place.

Setting "11n_disable=1" made the issue smaller but did not eliminate it, and 
the resulting network slowdown was unacceptable.
Trying "backport-iwlwifi-dkms" did not help either.

At this point this is a fresh install of 20.04 and the only workaround I
have is the firmware downgrade.

I am available for testing experimental "backport-iwlwifi-dkms" versions
if needed.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-12 Thread Zed Freejack
Update after running 5.6.7-050607-generic for more time now. 
Despite my initial enthusiasm, I cannot recommend updating to 
5.6.7-050607-generic wholeheartedly. The wifi and the system is snappy, but the 
fans are running 24/7 and when running form battery the battery life time is 
not good. Estimated a third of the time from the good old times of Kubuntu 
19.04... Investigations with tlp/powertop show a lot of power consumption from 
"Network interface: wlp59s0 (iwlwifi)" and "btusb" on light work load.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-12 Thread paoletto
got the driver crash now, after 2 days. so problem isn't fixed in -26.
I also think i found out how to reproduce: The problem happens basically 
immediately when connecting a BB10 device (Z10) to the machine with  wifi 
access point mode activated.

other devices (iOS, xperia) seem to only trigger sporadic Unhandled alg:
0x707 error but the driver keeps going

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-10 Thread paoletto
Adding that after about half hour i'm still getting
[ 1923.231089] iwlwifi :00:14.3: Unhandled alg: 0x71b

Usually a crash follows. So it might follow. But at least i have
transfered a wholly different amount of data in the meanwhile. -28 and
-29 would be crashing after 2 min or so.

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

Problem seems fixed in 5.4.0-26 with hwe package, loading .46 firmware.
So regression introduced in -28 and -29.

2020-05-10 Thread paoletto
Update: i tried again 20.04 live, and, with kernel 5.4.0-26, wifi seems to work 
alright.
So i installed 5.4.0-26 (i believe it was already replaced by -28 upon 
installation), but by doing so the wifi HW isn't even recognized, with dmesg 
looking for microcode. I'll keep investigating how does 20.04 live do it

Upgrading to 20.04 from 19.10 fixed this for me.

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

2020-05-06 Thread paoletto
thanks for the feedback Zed, i will give this a shot.
It's so sad to see how laggy canonical is in fixing such a serious bugs, but 
also how careless in introducing regressions such as this one.
I believe these wireless cards are extremely widespread, so i wonder how it's 
possible not to catch such a regression?

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-05 Thread Zed Freejack
My machine is a Dell XPS 15 9570 with an Intel Wireless-AC 9260.
Worked fine with Kubuntu 19.04 and 19.10. Later on on 19.10 (I believe 
5.3.0-51-generic) I got loads of hang ups and Wifi drop outs (seconds to 
minutes). Thought it was the swappines problem or the wifi problem of the 
kernel. Was adventurous and upgraded to Kubuntu 20.04 pretty early. Wifi went 
from bad to terrible to not usable (5.4.0-28-generic) 

A few days ago installed the mainline kernel following this instruction.
How to upgrade kernel to latest version on Ubuntu 20.04 Focal Fossa Linux
https://linuxconfig.org/how-to-upgrade-kernel-to-latest-version-on-ubuntu-20-04-focal-fossa-linux

Because the kernel is not signed I had to disable secure boot in the
UEFI. Got to sign the kernel later on...

Now running 5.6.7-050607-generic since a few days and am quite happy.
Snappy system, reliable WiFi. Fingers crossed.

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh

2020-05-05 Thread paoletto
I tried, with kernel 5.4.0-28 from 20.04, to downgrade to -43 (and,
fwiw, also to 41 and 38, after which i stopped as none was working), but
no luck for me. I might try to boot 5.3.0 which i still have to check if
that helps at all..

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-05 Thread Horst Baerbel
@paletto: Yes, I know. But I had the -43 version installed as the first
version lower than -46 and that one is working fine for me atm. I had
some messages "iwlwifi :0a:00.0: Unhandled alg: 0x707" during
bootup, but WiFi is working fine for me at 2.4 and 5GHz. I'm at kernel
5.3.0-52-generic now due to enabling the ubuntu-proposed repo, but this
did NOT fix the WiFi behaviour - it was definitely downgrading the
firmware to -43.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-05 Thread paoletto
5.4.0-29-generic seems so far to improve the situation a little.
It takes longer for the driver to crash, but it eventually does.

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

2020-05-04 Thread Horst Baerbel
I have to correct myself. Switching on ubuntu-proposed packages did NOT
help, it was switching to 2.4GHz that made the WiFi crash less often...
What really helps is creating a link from the -46 to the -43 firmware as
mentioned in

and the fw on the intel page is version .34, while in /lib/firmware is .46, so 
not sure that is gonna help

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-05-01 Thread Horst Baerbel
Switching on eoan-proposed fixes it for me. This removes the
iwlwifi-9260-th-b0-jf-b0-46.ucode file and updates the kernel to
5.3.0-52. backport-iwlwifi-dkms is still at 7906, so not sure where the
fix is, but it will do for now...

2020-04-29 Thread Wouter Blancquaert
I can confirm I'm also suffering from this using Ubuntu 20.04.

Manually downloading the firmware as mentioned in the description and
sym-linking resolves the issue for me.

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

2020-04-18 Thread Nikita Seleznev
I'm sorry that I am not your brother, since I've updated to dev Ubuntu 20.04 
and still face the same issue.
After trying all meaningful ways to fix the problem (switch kernel, switch 
firmware), now I have to get rid of 9260 and use USB Wi-Fi dongle. Amaizing.

My brother had this problem solved in the next Ubuntu release (20.04)
(probably due to the fact the kernel version is 5.4+)

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-04-13 Thread otheos
This is still NOT FIXED!!!

Kernel: 5.3.0-46-generic

After a restart from Windows the problem is persistent. It may take a
complete shutdown, maybe a couple for restarts from Ubuntu back to
Ubuntu before it stops.

This was not a problem in 5.2 It is a huge failure of the kernel team
and the driver supplier to have this issue.

We run 90 laptops with the 9260 wifi, all on ubuntu, all users are using
more Windows as a result.

Please have a serious look into this. Clearly dual boot systems suffer
more than ubuntu-only systems. The fact that the issue is more prominent
(or always present) after a restart from Windows indicates that some
settings from Windows persists in Linux and makes the driver crash.

Any laptop with the 9260 can reproduce this issue, please have a look.

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-02-05 Thread Michael
I am using a Thinkpad E490 with the Intel 9260 wireless card, Kubuntu
19.10 and kernel 5.3.0-29-generic.

05:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)

I have tried several iwlwifi module options (11n_disable=1,
11n_disable=8, power_save=0, bt_coex_active=0, lar_disable=1,
swcrypto=0), older firmwares, as well as the dkms backport module. I
have tested nearly all variations and the error did not disappear.

This is what I can summarize:

The error occurs after booting Windows (Fast Boot is disabled - which has no 
positive effect) and then booting Linux afterwards.
The error is quickly reproducible using speedtest.net (thanks @Hairong Zhu 
(hrzhu)) or transferring a larger file of any kind.

The ONLY solution to the problem in my case is: 
Shutting the system down and removing the power adapter. Then boot Linux and 
the error is gone (no module options, current firmware 
iwlwifi-9260-th-b0-jf-b0-46.ucode, kernel 5.3.0-29-generic).

Never boot from Windows to Linux without powering down completely, then
you should be fine until a fix is available.

2020-01-31 Thread Hairong Zhu
Apparently, 5.4.16 with the above patch included solves the problem.
Before this patch, performing a speedtest.net test or downloading a
large file almost guarantees to reproduce the problem. Please backport
the patch to Ubuntu's 5.3 kernel.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-01-29 Thread otheos
Latest kernel solves this for 19.10. Tested on both my systems. As far
as I'm concerned this should be marked resolved. Hopefully we'll keep it
that way in the future. Thanks everyone for all your help, and the
developers for sorting this out. Much appreciated.

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

Seems that a patch has been finally submitted:
https://lore.kernel.org/stable/20191203080849.12013-1-emmanuel.grumb...@intel.com/t/

Upstream bug report is at
https://bugzilla.kernel.org/show_bug.cgi?id=204873 and
https://bugzilla.kernel.org/show_bug.cgi?id=205001 (the latter one
including a git bisect).

Can this patch be backported?

  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-01-05 Thread Nader Nooryani
I have a Lenovo Yoga S730 (marketed as Lenovo ideapad 730s in the US,
mine is European) with the 9260 card and I can confirm that the same
issue affects me.

The wifi works fine in Windows 10. The only way I've managed to resolve
the issue is by adding 11n_disable=1, but this caps my speed to 54mb
which is too much of a compromise.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-01-04 Thread phantomatlas
I am using OpenSUSE Tumbleweed on this platform and the AC9260 works
flawlessly.  It wakes after sleep, reconnects without issue, performs
excellently on standard WiFi or 5G alike, over sustained sessions.
Curiously, it is using the exact same set of firmware files under kernel
5.3.

To me, this means that it is something particular to Ubuntu and its
downstream variants.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2020-01-04 Thread Patrick Mandigo
I've seen this problem too.  I purchased a Lenovo ideapad 730s that has
the 9260 wifi chipset and it was unusable with ubuntu 19.10, any
significant internet download would cause the pointer to freeze and the
entire system to come to a halt (but resume working again after 30-45
seconds).  I couldn't complete a speedtest.com speed test because the
entire system will completely free and the test would fail.  A buddy at
work who has the same model said he had the problem too (with fedora,
not sure which kernel).  I installed 19.04 instead and mentioned to him
19.04 works great for me, but he told me even under 19.04 eventually an
update will break the wifi and cause this halting behavior and sure
enough, after 19.04 worked for weeks and weeks today suddenly I started
having the same freezing behavior under 19.04, whenever I do any
significant internet activity the entire system halts for 30 or so
seconds, mouse pointer disappears and everything.

I copied iwlwifi-9260-th-b0-jf-b0-34.ucode to /lib/firmware but that didn't 
seem to do anything, maybe there's something I need to do to install it?  When 
I type modinfo iwlwifi |grep 9260
I get 
firmware:   iwlwifi-9260-th-b0-jf-b0-46.ucode

so maybe it's still using the buggy broken one.

It does seem like I can work around by adding the lines above that
include 11n_disable=1 although download performance is pretty poor, 30mg
down instead of 300mg down that I was seeing for weeks while it was
working.  This is such a common chipset, it's frustrating that there's
still no real fix for it.

I can confirm just disabling the 11n setting does indeed work as a
workaround, tried on an XPS 15 9570 with that WiFi card.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-12-22 Thread Daniel
I've been having the same problem, the workaround I have is to use older
firmware.


download:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/snapshot/linux-firmware-
e58cbf78678fd872d0cf7ab858ba0030cd8695b0.tar.gz

and install the ./iwlwifi-9260-th-b0-jf-b0-34.ucode blob to
/lib/firmware


I have also added an /etc/modprobe.d/wifi.conf with the following:
options iwlmvm power_scheme=1
options iwlwifi swcrypto=0 bt_coex_active=0 power_save=0 11n_disable=1

However I know that none of them except the 11n_disable option actually
fixed the problem -- disabling the 11n setting MIGHT be a workaround as
well, however I haven't tested with the broken firmware to know.   [the
reason is because other bug reports have confirmed the older firmware
alone fixes the issue].

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-12-22 Thread Daniel
I've been having the same problem, the workaround I have is to use older
firmware.


download:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/snapshot/linux-firmware-
e58cbf78678fd872d0cf7ab858ba0030cd8695b0.tar.gz

and install the ./iwlwifi-9260-th-b0-jf-b0-34.ucode blob to
/lib/firmware


I have also added an /etc/modprobe.d/wifi.conf with the following:
options iwlmvm power_scheme=1
options iwlwifi swcrypto=0 bt_coex_active=0 power_save=0 11n_disable=1

However I know that none of them except the 11n_disable option actually
fixed the problem -- disabling the 11n setting MIGHT be a workaround as
well, however I haven't tested with the broken firmware to know.   [the
reason is because other bug reports have confirmed the older firmware
alone fixes the issue].

  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-12-15 Thread otheos
Here's an update. The problem persists with 5.3.0.24 (and with Pop_os
5.3.0-7625).

However, I have noticed that after a few days of use, without any
further change, the problem disappears. Until I boot to Windows. After
that, the problem appears again, stronger than ever.

Now this may explain a couple of observations. Maybe the problem is a
result of some setting Windows does to the adapter through their driver,
that persists when linux boots and doesn't work very well. Maybe once
this setting is undone after a number of linux boot ups (and no
windows), the problem goes away until Windows boots up and restarts the
whole chain of events.

Also maybe this explains why some people (who don't dual boot) don't
have the issue at all.

Sorry for the lack of technical description here. However the
correlation between booting Windows and then Linux and the appearance of
the problem is very strong. Whether that correlation also means
causation is left for the more technical people to address.

Thank you.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-11-14 Thread otheos
All this while trying to run apt upgrade (250MB download). 
Thank you.

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

I am having the same problem, wifi adapter not detected Ubuntu 19.10 / Intel 
9260. 
[4.778071] Loading modules backported from iwlwifi

  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

Same error here with Ubuntu 19.10 / Intel 9260. Never happened before
(Ubuntu 19.04).

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-10-29 Thread Lars Gebraad
I'd like to add that this bug also occurs exactly as described (full
system freeze when heavy traffic begins) on Pop!_OS 19.10 with kernel
5.3 and the 9260ac.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-10-29 Thread otheos
Thanks.

The message when unresponsive is the same as the original posted at the
beginning.

As for hardware, I have two systems with the 9260ac, no other common
components, both have the same issue.

This is a problem with kernel 5.3 and the 9260ac chip. It never happened
with previous kernels. Booting to 5.0.32 (left over from ubuntu 19.04)
does not cause this.

Thanks.

[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]

2019-10-28 Thread You-Sheng Yang
@otheos, could you help collect logs when the system becomes
unresponsive? You can paste the dmesg of the last boot after rebooting.

I cannot find same hw for test, so it would be on your own. You might
want to file a bug on https://bugzilla.kernel.org/ concurrently.

Title:
  iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem
  [8086:0010]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 19.10
  Kernel 5.3.0-18-generic
  Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.

  Expected: Wifi connects, uploads/downloads as normal

  Symptom: Wifi connects, as soon as an upload/download (any heavy
  traffic) start, the system comes to a crawl, becomes barely usable,
  and I end up opening a prompt to reboot.

  The system is unusable. This happens even with the Live USB version.

  The only solution I found was to download a different (newer) firmware.
  Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

  This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz

  I then manually copy the contained firmware to /lib/firmware, remove
  all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
  that the kernel expects to load.

  This completely resolves the issue.

  This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh 
installs):
