[Kernel-packages] [Bug 1381625] Re: Adjust brightness to lowest value caused screen whole black

[Kai-Heng Feng]

There are some scenarios make turning off brightness not desirable, e.g.
an AIO user changes brightness to the lowest level in unity-control-
center, he can't change it back if his keyboard does not have brightness
hotkey.

Since we can't ensure that all graphics driver have the same mechanism
and each one of them does not change, I think it's a better choice to
let userspace program controls a consistent policy.

[Kernel-packages] [Bug 1381625] Re: Adjust brightness to lowest value caused screen whole black

[Kai-Heng Feng]

Yes, we can use that approach on unity-settings-daemon, with some minor
modification to make xbacklight works.

My intention to make it configurable is because there was a Braswell
laptop with a cheap panel, which needs at least 5% max brightness to
make it barely visible. For OEM projects, to solve problems like that, a
minimum brightness setting can be a generic and convenient way to make
preloaded Ubuntu more polished.

That being said, most panel works just fine with brightness value 1 in
my experience.

  But this pairing doesn't work very well. Mouse is seen but pairing fail.
  More information: https://bugzilla.kernel.org/show_bug.cgi?id=104011#c5

  This is due to udev rule that use "hcitool" to power on device.

[Kernel-packages] [Bug 1672144] Re: ifup service of network device stay active after driver stop

[Kai-Heng Feng]

It works on linux 4.11-rc3.
After kernel bisect, this commit fixes the issue:

commit 91864f5852f9996210fad400cf70fb85af091243
Author: Andrey Vagin 
Date:   Sun Mar 12 21:36:18 2017 -0700

net: use net->count to check whether a netns is alive or not

The previous idea was to check whether a net namespace is in
net_exit_list or not. It doesn't work, because net->exit_list is used in
__register_pernet_operations and __unregister_pernet_operations where
all namespaces are added to a temporary list to make cleanup in a error
case, so list_empty(>exit_list) always returns false.

Reported-by: Mantas Mikulėnas 
Fixes: 002d8a1a6c11 ("net: skip genenerating uevents for network namespaces 
that are exiting")
Signed-off-by: Andrei Vagin 
Signed-off-by: David S. Miller 

And it's also included in 4.10.5 stable tree, so it'll land to 17.04's linux 
kernel soon.
You can try 4.10.5 mainline kernel at here:

[Kernel-packages] [Bug 1664602] Re: Using an NVMe drive causes huge power drain

[Kai-Heng Feng]

@Dave,

For Zesty, it's already in the tree.
For Yakkety, I already sent patches to kernel-team ML.
For Xenial, I'd like to see if there's any regression after some real world 
usages in Yakkety and Zesty - after all the patch author made a blacklist table 
for a reason. If everything goes smoothly, I'll backport it to Xenial.

My bad.
C-State will be in next release,
P-State is not yet in Xenial's kernel tree.

I think you need to ask the driver author directly. I have zero clue on
how M560 works because I don't own one.

  Wrong button's map for Logitech M560

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I opened this bug a long time ago for Ubuntu 15.10. Now I installed a
  fresh Ubuntu 17.04 beta 2 and used xev to detect the button codes for
  this mouse and still use the wrong codes.

  Some mouses come with buttons on the wheel, so you can move the wheel
  to left and right and the mouse execute clicks.

  The problem is: to this clicks work on browser as back and forward
  functions, the buttons need to produce the codes 8 (back) and 9
  (forward). I know that because I also have a Logitech M325 mouse which
  has buttons on wheel's side and works out-of-the-box on the browser,
  emitting codes 8 and 9.

  The Logitech M560 mouse has this buttons on wheel's side, but produces
  codes 6 (left side) and 7 (right side). So out-of-the-box, this
  wheel's side buttons just work to scroll for left and right. Even this
  is less useful than "back" and "forward" browser's buttons, I could
  agree if the lateral buttons (code 10 and 11), do the "back" forward"
  functions, but I think the best option is to remap the wheel's side
  buttons to code 8 and 9, to work as back and forward.

[Kai-Heng Feng]

Hi Andrew,

You need to boot to 4.4.0-XX kernel instead of mainline kernel.

The latest mainline kernel is for testing only - you can safely remove
those kernels after testing is done.

To remove mainline kernels, you can run something like this:
$ sudo apt purge $(dpkg -l | grep 041100rc2 | awk '{print $2}')

Do the same for other mainline kernels you installed for testing.

  Fresh install, 10 days old, updated yesterday so software/kernel

  However,
  Pressing Function plus F2 does not turn off wireless
  Pressing Function plus F3,F4 do not change brightness
  Function plus F5 does not change output to LCD or Monitor
  Pressing Function plus F6 does not toggle touchpad (a separate bug in this

  Function plus F11 does not turn off bluetooth
  Function plus F12 does not disable the camera

  Please let me know if you need any further troubleshooting

[Kernel-packages] [Bug 1630324] Re: Broadcom wifi dies in 60s cycles with 4.8 kernel

[Kai-Heng Feng]

Does newer or older Linux kernel work without this issue?

Is the issue linked to "brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 
0x30)"?
I can see this message popped out several times, but the network is still 
connected.

  Broadcom wifi dies in 60s cycles with 4.8 kernel

Bug description:
  I have a Dell XPS 13 9350 with a Broadcom wifi adapter. Wifi connects
  fine, but dies for around 5-10s (the signal dies completely, tools
  like wavemon show "no interface data") in regular cycles of about 60s.
  dmesg logs the same brcmfmac errors every minute or so: "brcmfmac:
  brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)".

  network-manager's icon doesn't change however (remains as if the
  adapter was connected).

  This issue started to affect me when using kernel 4.8 on Ubuntu 16.04.
  I previously used kernel 4.7 and did not experience this bug.

  I booted the 16.10 daily build and experienced exactly the same
  errors.

[Kernel-packages] [Bug 1523108] Re: Bluetooth doesn't work on ASUS Zenbook UX301LAA

[Kai-Heng Feng]

Please give mainline kernel >= v4.11-rc3 a try, it has a patch seemingly
relevant to your case:

commit 71050ae7bf83e4d71a859257d11adc5de517073e
Author: João Paulo Rechi Vita 
Date:   Mon Feb 20 14:50:22 2017 -0500

platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDT

We can backport the patch if it works.

Sounds like there's still something wrong here?

Can you elaborate what's the incorrect behavior in 4.11-rc3?

[Kai-Heng Feng]

Well, this is not a fully functional driver yet, but it should help us
grab enough information to write a working driver.

Please follow these steps after you run `make`:

$ sudo modprobe wmi
$ sudo insmod gigabyte-wmi.ko

Then press FN+F1 to F12 (except sleep and volume control)
Attach output of `dmesg` here.

Does your system have a touchscreen?
Does it have the same stuttering issue under heavy graphics load?

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

[Kai-Heng Feng]

Do you have any alsa/pulseaudio config?

This can be quickly verified by running "vanilla" Ubuntu.

16.04: http://cdimage.ubuntu.com/xenial/daily-live/current/
17.04: http://cdimage.ubuntu.com/daily-live/current/

If both of them work, then it's probably related to your config setting.

  It seems that we cannot expect this before kernel 4.11.

  Additionally my laptop CPU does never go under PC3 power saving state, 
powertop says. I don't know if it's related.

Look like you don't have 'linux-image-extra-4.4.0-67-generic' installed.

I guess the 'linux-generic' metapackage somehow got removed. Please

Hmm, no iwlwifi, no wlp* interface.

Can you attach the output of `lspci -nnk`?
And output of `find /lib/modules | grep iwlwifi.ko`

@Paul

When the touchpad stuttered, did you see anything like 'overhead' or
'throttled' in dmesg?

[Kai-Heng Feng]

Looks like asus-wmi and asus-nb-wmi are both correctly loaded.

Can you add "asus-wmi.dyndbg=+p asus-nb-wmi.dyndbg=+p" to kernel
parameter and reboot?

Press the non-functional hotkeys and upload the output of 'dmesg'.

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Kernel-packages] [Bug 1674390] Re: Kernel 4.4.0-67 Defaults to ACPI-cpufreq rather than P-State - Dell Precision 5520

[Kai-Heng Feng]

Hi Carl,

Xenial kernel with intel_pstate Kabylake support to test is at
http://people.canonical.com/~khfeng/lp1674390/

commit 7791e4aa59ad724e0b4c8b4dea547a5735108972
Author: Srinivas Pandruvada 
Date:   Thu Feb 25 15:09:19 2016 -0800

cpufreq: intel_pstate: Enable HWP by default

If the processor supports HWP, enable it by default without checking
for the cpu model. This will allow to enable HWP in all supported
processors without driver change.

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[Kai-Heng Feng]

The information is quite helpful, the keys didn't generate any
interrupts.

You need to escape the double quote, i.e. acpi_osi=\"Windows 2012\"

  ASUS G752VS: Touchpad and Fn keys not working (Ubuntu
  16.04.1/16.10/17.04)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Non-Optimus laptop ASUS G752VS-GC063D-CST256.
  17.3" FHD LED 1920x1080, Intel Core i7-6700HQ (3.50Ghz), 16GB DDR4, 256GB M.2 
NVMe SSD + 1TB HDD 7200rpm, DVDRW-DL, Nvidia GTX1070 8GB GDDR5, Wifi

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Kernel-packages] [Bug 1672439] Re: No C-State Deeper than C3 utilized by Kaby Lake 7820HQ in Precision 5520

[Kai-Heng Feng]

No, that's why I built a slightly newer kernel, 4.4.0-68, so it won't
mess with the current release kernel, 4.4.0-66.

It's okay if don't want to test it, I already tested it on Precision
5520 at my hand.

The problem lies here is, 5520 has several different configs, I want to
make sure the patch works on your machine. Otherwise what's the point?

I assume the bluetooth symptom you saw mainly relates to the non-
matching firmware is still in the chip, a cold boot instead of warm
reboot should circumvent it.

You should remove the custom kernel and use the official Ubuntu kernel.

The deeper C state patch should be included soon.

[Kernel-packages] [Bug 1664602] Re: Using an NVMe drive causes huge power drain

[Kai-Heng Feng]

@Dave

I was wrong, you are right, it's not a clean cherry-pick.

I picked 7ac8b7abdb8d903c83fa15cfd952316e824fe6f3 from nvme tree (which
can be clean applied) instead of
bd4da3abaabffdd2472fb7085fcadd5d1d8c2153 from master.

The later one's diff contextually depends
8a9ae523282f324989850fcf41312b42a2fb9296, which is not a functional
dependendency to APST, so the conflict can be easily resolved.

Bug description:
  PCIe NVMe drives are very common in new laptops. The Zesty's kernels 
(including latest 4.10 rc8 from CKT PPA) does not support APST (autonomous 
power state transitions). A patch does exist :
  http://lists.infradead.org/pipermail/linux-nvme/2017-February/008051.html

  It seems that we cannot expect this before kernel 4.11.

  Additionally my laptop CPU does never go under PC3 power saving state, 
powertop says. I don't know if it's related.

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[Kai-Heng Feng]

Uh, ok, my bad, asus-wmi doesn't print any information when key is
pressed.

So let's test the following:

1. Check if function key generate anything:
$ show-key -s

2. Check if function key generate anything:
$ acpi_listen

3. Add kernel parameter and test if one of the following works:
acpi_osi=! acpi_osi="Windows 2015"
acpi_osi=! acpi_osi="Windows 2012"
acpi_osi=! acpi_osi="Windows 2009"

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

[Kernel-packages] [Bug 1674390] Re: Kernel 4.4.0-67 Defaults to ACPI-cpufreq rather than P-State - Dell Precision 5520

[Kai-Heng Feng]

Thanks for your test.

There is a directory 'intel_pstate' under '/sys/devices/system/cpu', it
only exists when pstate driver is in use.

C State for Kabylake will be included in next release after 4.4.0-69.

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[Kai-Heng Feng]

It's in https://bugzilla.kernel.org/show_bug.cgi?id=112531 comment #16.

Add this to kernel parameter:
acpi.trace_state=enable dyndbg="file ec.c +p"

If you make the change in /etc/default/grub, need to escape the quote as well:
acpi.trace_state=enable dyndbg=\"file ec.c +p\"

Bug description:
  Non-Optimus laptop ASUS G752VS-GC063D-CST256.
  17.3" FHD LED 1920x1080, Intel Core i7-6700HQ (3.50Ghz), 16GB DDR4, 256GB M.2 
NVMe SSD + 1TB HDD 7200rpm, DVDRW-DL, Nvidia GTX1070 8GB GDDR5, Wifi

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

Bug description:
  Ever since the 4.4.0-53 kernel update the touchpad and trackpoint have 
behaved erratically on my Dell Precision 7510:
  * The trackpoint moves WAY too fast and there don't seem to be any parameters 
I can change in xinput to fix this. It is essentially unusable.
  * The touchpad starts with parameters set incorrectly.
  * Touchpad tap to click is now turned on again and is very sensitive. This I 
can change through xinput but the change is still odd.
  * The two finger scrolling is set incorrectly to be highly sensitive. This I 
can also change through xinput.
  * Two finger scrolling still activates often during normal use of the 
trackpad. To the extent that I had to turn off two finger scrolling to stop 
inadvertent scrolling.

  All of the above behavior is new going from 4.4.0-47 to -53.
  Previously this all worked perfectly on this machine.

  Seems to be symptoms noted by these other users on askubuntu here as
  well: http://askubuntu.com/questions/862527/laptop-stick-mouse-
  problems-after-linux-4-4-update-on-14-04

  The touchpad symptoms I seem to be able to work around my changing
  xinput parameters, but the trackpoint I have not been able to fix at
  all (which is sad since that is my primary mouse device normally).
  Would appreciate any suggestions as to how to revert the old behavior.

  So i blacklisted the kernel module with:
  echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

  and used the lwfinger driver from github again.

  So with rtl8xxu driver wifi card does not work on normal boot but does
  work when recovering from suspend to ram.

  Thank you. Bye.

[Kernel-packages] [Bug 1653456] Re: ASUS G752VS: Touchpad and Fn keys not working (Ubuntu 16.04.1/16.10/17.04)

[Kai-Heng Feng]

Probably because the WMI driver is not loaded.

Please install acpica-tools and run acpidump,

$ sudo apt install acpica-tools
$ sudo acpidump > acpi-dump

Attach acpi-dump file.

Status in linux package in Ubuntu:

Bug description:
  Non-Optimus laptop ASUS G752VS-GC063D-CST256.

  Hello, after experimenting few days ago with Ubuntu 16.04.1, 16.10 and
  17.04, among other problems I found that touchpad and Fn keys (all
  except volume control) doesn't work on my brand new ASUS G752VS.

  It is very hard even to try Ubuntu 16.10 and 17.04 because of the
  missing mouse pointer. This problem must be related to a video driver
  because if after installing one is capable to install Nvidia drivers -
  problem is solved. This problem doesn't exist both while trying and
  installing Ubuntu 16.04.1!

  I'm currently on Windows 10, and this bug report is made from Ubuntu
  16.04.1 LiveCD.

  experiencing the same symptoms with the same model laptop except with
  a 512GB Samsung. Prior to manually disabling APST the drive would die

There's no key event in the log, maybe I am wrong here...

Can you run `acpi_listen`, then press those not working hotkeys?
Does it show anything?

[Kernel-packages] [Bug 1507472] Re: [MacbookPro12, 1] Suspend resumes immediately due to xhci driver

[Kai-Heng Feng]

Hi NeoTheThird,

First, does this happen on latest mainline kernel?
If yes, then please do the following -
Find all devices under XHCI hub by issueing `lsusb -t`, here's what on my 
laptop:
$ lsusb -t
/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/11p, 480M
|__ Port 3: Dev 2, If 0, Class=Wireless, Driver=btusb, 12M
|__ Port 3: Dev 2, If 1, Class=Wireless, Driver=btusb, 12M
|__ Port 4: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 12M
|__ Port 5: Dev 10, If 0, Class=Video, Driver=uvcvideo, 480M
|__ Port 5: Dev 10, If 1, Class=Video, Driver=uvcvideo, 480M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/3p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M

There are two modules under 'xchi_hcd', 'btusb' and 'uvcvideo'.

Please execute `sudo modprobe -r X`, replace X with modules under
xhci_hcd, 'btusb' & 'uvcvideo' in my case.

Suspend and check if this issue persists.

Title:
  [MacbookPro12,1] Suspend resumes immediately due to xhci driver

Status in linux package in Ubuntu:
  Triaged

Bug description:
  On my MacbookPro12,1 with Wily and Linux 4.2, by default the kernel
  successfully suspends but then immediately resumes again. The problem
  seems to be the XHCI controller causing spurious ACPI wakeups.

  Also, the Broadcom wifi module seems to have problems with
  suspend/resume, so I am also unloading the `brcmfmac` module prior to
  suspend and loading it again after resume.

  WORKAROUND: Disable XHC1 prior to sleeping:
  > # echo XHC1 > /proc/acpi/wakeup

[Kernel-packages] [Bug 1678590] Re: Dell Inspiron on kernel 4.10 : battery detected only after AC power adapter event

[Kai-Heng Feng]

Seems like it's the same: https://bugzilla.kernel.org/show_bug.cgi?id=105721.
Please test if kernel option 'acpi_rev_override' works.

  Dell Inspiron on kernel 4.10 : battery detected only after AC power
  adapter event

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  I already reported the bug here:
  http://www.spinics.net/lists/linux-acpi/msg73101.html

  When I boot a Dell 15" serie 7000 with or without it AC power adapter
  no battery is detected:

  acpi -i -b -a
  Adapter 0: off-line

  As soon as I plug or unplug the AC adapter, the battery is detected:
  acpi -i -b -a
  Battery 0: Charging, 62%, 01:13:00 until charged
  Battery 0: design capacity 3950 mAh, last full capacity 3850 mAh = 97%
  Adapter 0: on-line

  cat /proc/cmdline

  4cd8-a1d2-caf2bd33de1b ro acpi_osi=Linux quiet splash vt.handoff=7

  
  I've tried with and without acpi_osi=Linux but it makes no difference.

  Attached : dmesg and dsdt in 
http://www.spinics.net/lists/linux-acpi/msg73101.html
  I think that acpi_osi=Linux used to do the trick but it does not work on

Can you attach the dmistring of your machine? We can make the workaround
into kernel itself.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The laptop Clevo P650RS has a Synaptics touchpad but it is not
  detected by the kernel 4.8.0-27 on Ubuntu 16.10. There is no entry in
  /proc/bus/input/devices matching it. I installed Windows to check if
  it works at all, and it does. Windows identifies it as ACPI/SYN1219.

  WORKAROUND: Use kernel boot parameter:
  i8042.reset

Title:
  BLE pairing fail

Status in bluez package in Ubuntu:
  Incomplete

Bug description:
  On 15.10 we now have bluez 5 so we can pair BLE devices like the
  Microsoft Arc Touch Bluetooth Mouse.

  But this pairing doesn't work very well. Mouse is seen but pairing fail.
  More information: https://bugzilla.kernel.org/show_bug.cgi?id=104011#c5

  This is due to udev rule that use "hcitool" to power on device.
  Hopefully, bluez 5.35 has a new parameter "AutoEnable" who can be used 
instead of udev rules.

  here is a commit with this parameter: 
http://bazaar.launchpad.net/~guilhem-fr/bluez/autoenable/revision/138
  And a ppa to test it:

[Kernel-packages] [Bug 1678590] Re: Dell Inspiron on kernel 4.10 : battery detected only after AC power adapter event

[Kai-Heng Feng]

Yes.

Though I think use 'acpi_rev_override' should be a better alternative in
the meantime.

Status in linux package in Ubuntu:

Bug description:
  Hi,

  I already reported the bug here:
  http://www.spinics.net/lists/linux-acpi/msg73101.html

  When I boot a Dell 15" serie 7000 with or without it AC power adapter
  no battery is detected:

  acpi -i -b -a
  Adapter 0: off-line

  As soon as I plug or unplug the AC adapter, the battery is detected:
  acpi -i -b -a
  Battery 0: Charging, 62%, 01:13:00 until charged
  Battery 0: design capacity 3950 mAh, last full capacity 3850 mAh = 97%
  Adapter 0: on-line

  cat /proc/cmdline

  BOOT_IMAGE=/boot/vmlinuz-4.10.0-13-generic root=UUID=42930a1e-fbdc-
  4cd8-a1d2-caf2bd33de1b ro acpi_osi=Linux quiet splash vt.handoff=7

  
  I've tried with and without acpi_osi=Linux but it makes no difference.

  Attached : dmesg and dsdt in 
http://www.spinics.net/lists/linux-acpi/msg73101.html
  I think that acpi_osi=Linux used to do the trick but it does not work on 
vmlinuz-4.10.0-13-generic

  Hello,
  Randomly the touchpad pointer moves to one end of the screen, and we have 
found that when it does message appears in dmseg:

  psmouse serio1: Explorer Mouse at isa0060/serio1/input0 lost
  synchronization, throwing 3 bytes away.

  Sometimes it happens after 10 minutes of use, sometimes it happens after 3 or 
4 hours.
  We have tested several computers with touchpad "Hantick", that use the both, 
the evdev library and the libinput library. It always happens randomly.

Does the touchpad keeps working after the kernel message?
At what situation it doesn't work?
At waht situation it works?

[Kernel-packages] [Bug 1655978] Re: Bluetooth not working in Ubuntu 16.4 LTS

[Kai-Heng Feng]

The driver should work just fine, you only need correct firmware.

IIUC, due to license issues, Broadcom Bluetooth firmware is not in 
linux-firmware.
You need to extract firmware from Windows driver yourself, then convert the 
firmware from HEX to HCD.

A quick google shows that someone already did all the works [1], but I
don't know if it's legal or not, so use it on your own discretion.

[Kernel-packages] [Bug 1678184] Re: APST quirk needed for Samsung 512GB NVMe drive

[Kai-Heng Feng]

@Andy,

Are you willing to help me testing if ps2/ps3 works?
My guess is that ps2 (most powersaving operational state) works but not ps3/ps4.

So I need your help to try kernel parameter
"nvme_core.default_ps_max_latency_us=250", and
"nvme_core.default_ps_max_latency_us=3000".

Thanks!

Title:
  APST quirk needed for Samsung 512GB NVMe drive

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  APST support just landed in the latest Zesty kernel (4.10.0-14.16) as
  part of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602.
  That patch has a quirk for certain 256GB Samsung drives found in Dell
  laptops that do not behave well when APST is enabled. I am
  experiencing the same symptoms with the same model laptop except with
  a 512GB Samsung. Prior to manually disabling APST the drive would die
  and system would go down in flames with I/O errors within 20 to 40
  minutes of boot.

  Dell Inspiron on kernel 4.10 : battery detected only after AC power

Status in linux package in Ubuntu:
  In Progress

Bug description:
  Hi,

  I already reported the bug here:
  http://www.spinics.net/lists/linux-acpi/msg73101.html

  When I boot a Dell 15" serie 7000 with or without it AC power adapter
  no battery is detected:

  acpi -i -b -a
  Adapter 0: off-line

  As soon as I plug or unplug the AC adapter, the battery is detected:
  acpi -i -b -a
  Battery 0: Charging, 62%, 01:13:00 until charged
  Battery 0: design capacity 3950 mAh, last full capacity 3850 mAh = 97%
  Adapter 0: on-line

  cat /proc/cmdline

  BOOT_IMAGE=/boot/vmlinuz-4.10.0-13-generic root=UUID=42930a1e-fbdc-
  4cd8-a1d2-caf2bd33de1b ro acpi_osi=Linux quiet splash vt.handoff=7

  
  I've tried with and without acpi_osi=Linux but it makes no difference.

  Attached : dmesg and dsdt in 
http://www.spinics.net/lists/linux-acpi/msg73101.html
  I think that acpi_osi=Linux used to do the trick but it does not work on 
vmlinuz-4.10.0-13-generic

  USB stops working after a while (xhci_hcd :00:14.0: Timeout while

Bug description:
  On my laptop the kernel will sometimes drop the USB hub. After this,
  the laptop doesn't recognise any device plugged in to the USB ports -
  plugging and unplugging any device I've tried into any of the USB
  ports produces no response, not even dmesg entries.

  Strangely this also applies to bluetooth - it no longer works once USB
  has dropped (possibly the module is hung of the bus internally).

  Once this has happened only a reboot fixes it; I've not managed to
  find any combination of module unload/reload or suspend cycles to
  reinitialise things correctly.

  Also tested this with the mainline upstream kernel

Okay, can you test if one of the following kernel parameter works:
'asus-nb-wmi.wapf=0'
'asus-nb-wmi.wapf=1'

[Kernel-packages] [Bug 1682711] Re: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used

[Kai-Heng Feng]

Is cooling the NVMe is your goal? 4.10.0-19 already has NVMe APST
support. No sure if PCIe ASPM matters though.

Title:
  PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force /
  setpci used

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is somewhat similar in issue to lp#1377596.

  I have a "Lenovo ThinkCentre m900 Tiny" with an "Intel 600p" NVMe
  drive in it.

  As far as I can tell from dissembling the FADT PCIe ASPM is not set to
  disabled but the ports are not enabled in UEFI during boot.

  I also notice that the PCIe ASPM debug files are not in sysfs like
  they normally are ie: link_state

  I tried running the following manually but I think it must not be
  enough as the NVMe drive does not run any cooler as it does in a
  system with known working ASPM.

  setpci -s 00:1b.0 0x50.B=0x3
  setpci -s 00:1c.0 0x50.B=0x3
  setpci -s 01:00.0 0x80.B=0x3
  setpci -s 02:00.0 0x50.B=0x3

  I noticed via lspci that the root ports say ASPM not supported even
  though the FADT doesn't have them disabled. Is that the reason its
  still not working and how do I work around that issue?

  Also is there something specific I can tell Lenovo to do to fix this
  issue on their end, if it can't be worked around in Linux? I have an
  open case with them via the UEFI engineering team but so far its been
  slow going since I don't have anything concrete to tell them to fix.

  experiencing the same symptoms with the same model laptop except with

  APST quirk needed for Samsung 512GB NVMe drive

  APST support just landed in the latest Zesty kernel (4.10.0-14.16) as
  part of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602.
  That patch has a quirk for certain 256GB Samsung drives found in Dell
  laptops that do not behave well when APST is enabled. I am
  experiencing the same symptoms with the same model laptop except with
  a 512GB Samsung. Prior to manually disabling APST the drive would die
  and system would go down in flames with I/O errors within 20 to 40
  minutes of boot.

[Kernel-packages] [Bug 1678184] Re: APST quirk needed for Samsung 512GB NVMe drive

[Kai-Heng Feng]

The upstream author sent a patch set [1] according to this bug report
(thanks guys!). Looks like 4.11 will disable APST and make it opt-in,
and 4.12 will introduce a new quirk to avoid deepest power state.

I'll backport the patch set once it lands at linux-nvme tree.

[Kernel-packages] [Bug 1523108] Re: Bluetooth doesn't work on ASUS Zenbook UX301LAA

[Kai-Heng Feng]

The commit log says:
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.

This commit skips registering RFKill switches at all for these laptops,
to allow the asus-wireless driver to drive the airplane mode LED
correctly through the ASHS ACPI device. Relying on the presence of ASHS
and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least
21 different laptops.

Sounds like the LED should be off when Airplane mode is off...

  [MacBookPro11,1] Laptop wakes up while lid closed

Status in linux package in Ubuntu:
  Confirmed
Status in Debian:
  New

Bug description:
  Same behavior when using pm-suspend. It is hard to notice whether the
  laptop wakes up, especially because that does not always happen
  immediately. Getting to sleep takes up to 30 seconds. Hardware damage
  may be a result of waking up while lid is closed, for example if
  laptop is transported in a bag. I suspect that the problem comes from
  the Intel video driver. See extract from kern.log.

  WORKAROUND: Disable XHC1 in /proc/acpi/wakeup.

Title:
  No usb on resume from suspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My XPS13 running 14.04 sometimes loses its USB ports after resume from
  suspend. When this happens the entire bus seems dead - both external
  ports do not work, and internal USB devices (webcam, touchscreen) are
  also non-functional. Furthermore lsusb shows no devices attached.
  Rebooting or performing another suspend/resume cycle will clear the
  problem.

Title:
  Using an NVMe drive causes huge power drain

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Confirmed
Status in linux source package in Yakkety:
  Fix Committed
Status in linux source package in Zesty:
  Fix Released

Bug description:
  PCIe NVMe drives are very common in new laptops. The Zesty's kernels 
(including latest 4.10 rc8 from CKT PPA) does not support APST (autonomous 
power state transitions). A patch does exist :
  http://lists.infradead.org/pipermail/linux-nvme/2017-February/008051.html
  https://github.com/damige/linux-nvme

  It seems that we cannot expect this before kernel 4.11.

  Additionally my laptop CPU does never go under PC3 power saving state, 
powertop says. I don't know if it's related.
