After the engineer replaced the touchpad, it works in windows and even
in system diagnostics but not in ubuntu( either installed or from
pendrive). In cat /proc/bus/input/devices, it lists the touchpad, but
does not recognize it.

[Kernel-packages] [Bug 1531768] Re: [arm64] lockups when idle if tickless (nohz=on) is used

[Martin Pitt]

>- trusty and vivid kernels with nohz=off have survived for a full day
without any lockups.

They both hung last night.

So in summary: Neither nohz=off nor older kernels help here. This really
seems to be a matter of luck/what's going on on the host system.

** Summary changed:

- [arm64] lockups when idle if tickless (nohz=on) is used
+ [arm64] lockups some time after booting

  However, pretty much any LXD task that I do (I haven't tried much

Bug description:
  Killer 1525 wireless card doesn't work on Ubuntu Mate with stock drivers. It 
sometimes can detect networks, but cannot connect to WPA protected WIFI.
  "dmesg | grep ath" shows several thousand of lines "failed to start hw scan: 
-108". Problem can be fixed by following the steps outlined here:
  
http://www.killernetworking.com/support/knowledge-base/17-linux/20-killer-wireless-ac-in-linux-ubuntu-debian

  Please include correct board.bin and firmware-?.bin files to Ubuntu
  Mate 16.04 distro.

  In my case wifi worked after I deleted board.bin and firmware-4.bin
  both  /lib/firmware/ath10k/QCA6174/hw2.1/ and
  /lib/firmware/ath10k/QCA6174/hw3.0/ then copied
  firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 as firmware-4.bin and
  firmware-4.bin. Finally, I saved resulting board.bin, firmware-4.bin
  and firmware-5.bin to both /2.1/ and /3.0/ folders

Bug description:
  I am running 16.04 beta 2 on MacBookAir5,2. I tried to copy an El
  Capitan to it from an El Capitan MacBook Pro and every time I did, the
  copy would go for ~140M and then lock the network on the Air. I
  resolved it by restarting the Air's network. This is over WiFi.

Title:
  [Lenovo X220] SDXC UHS card slow performance

Status in linux package in Ubuntu:
  Expired

Bug description:
  Steps to reproduce:
   - Install ubuntu on Lenovo X220 laptop (checked with Linux Mint 17.3 (based 
on Ubuntu Trusty LTS) and LiveUSB of Ubuntu 15.10)
   - Insert and mount SDXC  UHS card.
   - Try to read some files from mounted card.

  Results:
   - Actual read speed is about 20 MB/s.
   - Expected speed is higher, because I checked the same card in the same 
laptop with external USB2.0 cardreader and it gives about 36MB/s and I think 
USB3.0 could give more.
   - Actually cardreader in X220 model connected via PCI-E bus, so the 
performance must be al least equal to USB reader, but it actually almost 2 
times lower.

  Some details:
   - I supposed this bug is relevant to #773524 bug, the solution was to lower 
down base frequency to 50 MHz.
  I checked my card in live 11.04 and it works fine, but the speed is even 
lower, about 11MB/s.

  Technical details:

  $ cat /proc/version_signature
  Ubuntu 4.2.0-30.36~14.04.1-generic 4.2.8-ckt3

  $ dmesg | grep mmc0
  [1.934510] mmc0: SDHCI controller on PCI [:0d:00.0] using DMA
  [2.012509] mmc0: new high speed SDXC card at address 59b4
  [2.014409] mmcblk0: mmc0:59b4 NCard 59.0 GiB

  $ dmesg | grep sdhci
  [1.929073] sdhci: Secure Digital Host Controller Interface driver
  [1.929076] sdhci: Copyright(c) Pierre Ossman
  [1.931077] sdhci-pci :0d:00.0: SDHCI controller found [1180:e822] 
(rev 7)
  [1.931611] sdhci-pci :0d:00.0: No vmmc regulator found
  [1.931613] sdhci-pci :0d:00.0: No vqmmc regulator found

  Note:
  After cold boot I see in dmesg
   SDHCI controller found [1180:e823] (rev 4)
  but after reboot or sleep it changes to
   SDHCI controller found [1180:e822] (rev 7)

  Proposal:
  It is possible to control MMC base frequency manually (i.e. by running 
sdhci-pci module with needed options) to check the performance on 4.2 kernel on 
200 MHz base frequency and be able to low it down for cards that requires that 
patch.

  Sometimes I see in dmesg
  sdhci-pci :0d:00.0: MMC controller base frequency changed to 50Mhz.
  which indicates that fix of #773524 bug works, but the performance with or 
without this message is the same.

[Kernel-packages] [Bug 1437492] Re: boot stalls on USB detection errors

[Dave Allan]

This patch doesn't seem to work for me in wily (Ubuntu 14.04.4). I've
tried both applying the patch to the current wily source (4.2.0-38.45)
and also compiling the master-next source for wily. Neither solves the
problem of the USB initialisation delay.

The patch integrates successfully and the kernel compiles fine. I've
also checked to ensure the correct (modified) USB options are enabled in
the kernel config. I wonder if there's something relatively obvious I'm
not doing?

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash

[Dmitry Mazur]

Hi, don't know where to post this (and my English is not so good,
sorry), but: i have the same problems with my bcm43142 (HP G4 250
laptop) + (4.4.0-24-generic #43-Ubuntu 16.04 64'bit' GNU/Linux) - it
drops connections per "any random time". Today (after many days of
wifipain) I've seem that ping drop so many packages, BUT not for the
first time - ONLY when u start ping anywhere for the second time after
`modprobe or .. wifi goes on?` ! So i have decided to check if terminal
will always ping ( * my router ip, cause don't be banned by anybody, of
couse) and what i've seen: NO DROPPING while pinging. at all. (also
packets AND wifi connection i mean + wifi signal meters "don't jump").
(64 bytes from 192.168.10.1: icmp_seq=6338 ttl=64 time=0.628 ms). but.
Before this i disabled ipv6 and don't change it back.. Tomorrow will
check with ipv6 and other options.. I know this is not a cure, but it's
working for me. What do next if i can help?

Bug description:
  [Impact]

   * bcmwl does not compile on new kernels (or HWE kernels)
   * bcmwl suffers from null reference bug 

  [Test Case]

   * public PPA provided to community and feedback
   * based on patch available to other distros
   * comment #42

  [Regression Potential]

   * for changes on kernel support it may not compile (tested with 3.2, 3.13, 
3.18 and 4.2)
   * for the null reference change -> proved to fix problem for community based 
on feedback

  [Other Info]

  Original bug description:

  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom 
/usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.

If none of y'all are seeing anything like this in the proposed kernel I
wouldn't be surprised if it has something to do with my setup, so this
bug probably shouldn't block the release.

  It's only happened once in the three times I've booted into the new

Title:
  there are several errors on booting my laptop (xubuntu 16.04 64 bits),
  ordering cycle broken

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Best I could think of is recording a video, so you see what I endure
  every time I power on the laptop:

  https://vid.me/9eRl

  it's comments are self explanatory:

  Booting on M7X-SUN

  00:39: those are several inode errors, those appear because I had to
  reboot the laptop several times (because the first or second time on
  powering the laptop I just got a blank screen).

  00:48: that huge list of things being loaded is nowehere in
  /var/log/syslog, dmesg or kern.log to be seen. Where do I find that
  information that tells me what is going in in plain text format? Green
  is OK, red is FAILED

  Right after the several inode errors some information about the
  ordering cycle appears: They read as follows (see #8 for more
  information):

  /dev/sda1: clean, 116918/19275776 files, 66284199/77094912 blocks
  [10.368134] systemd[1]: paths.target: job paths.target/start deleted to break 
ordering cycle starting with basic.target/start
  [10.368234] systemd[1]: systemd-ask-password-plymouth.path: Job systemd

basic.target/start
  [10.368324] systemd[1]: plymouth-start.service: Job 
plymouth-start.service/start deleted to break ordering cycle starting with 
plymouth-quit-wait.service/start

  the very first entrance (in yellow) reads: dependency failed for PNFS
  block

  01:21: from this moment on, blank screen with just a cursor. It stays
  like that usually for 30 to 40 seconds with no mention of tty1 (see
  next)

  01:38: thats tty1 asking me an username and if I enter it, a password,
  I usually don't write anything and let the laptop go on to login
  screen.

  02:01: blank screen (this is new, usually the login screen should
  appear now)

  03:00: not recorded, but log in screen appeared.

  I dont know if this is related to my other bug:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1589109 , because
  on shutting down I also don't see what is going on...

  somebody suggested to execute 'systemd-analyze plot > boot.svg' which
  does not show that huge list I mention on 00:48, but I append it here,
  as it may be useful for you...

  How Do I solve all those problems and get my fully 4 GiB of ram to work 
instead of the 2 just right now? Between 2 and 3 minutes just to boot a laptop 
is too much time.

update it was, but we're good now.

  50/50 chance for BCM43602 to come up correctly during boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My BCM43602 has a 50/50 chance during boot of ever becoming "ready"
  and pulling an IP address. The problem seems to be this "link is not
  ready" and "already exists" loop. The log I sent was one of the cases
  where things eventually worked. If I get unlucky, it simply repeats
  the "already exists" / "not ready" loop indefinitely.

  I get a similar situation when suspending/resuming. I've already
  pulled the firmware and stuck it under /lib (see dmesg output for
  version).

Bug description:
  snapd is seeded in all images in xenial by default and snaps are
  squashfs files.

  the snappy images need squashfs available at boot time and use
  official kernels.

  currently squashfs is the only module that forces us to re-pack
  initrds to add it everywhere for snappy images, in that light it would
  be really helpful to have squashfs built into the kernel instead of it
  being a module.

[Kernel-packages] [Bug 1584533] Re: Lenovo X220 unable to wlan after resume from sleep

[Rudolf Leitgeb]

In the mean time, there was a linux kernel upgrade in Ubuntu 16.04, and
whatever that kernel changed, I have not had connection failure ever
since. I would therefore cautiously mark this issue resolved for now.

About the suggested BIOS upgrade: there appears to be something messed
up on Lenovo's webpage: while version 1.42 is stated as available, the
download links provided on that page will provide version 1.40. One has
to guess the correct download URL to access the most recent BIOS
version:

BIOS version 1.42: 
https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8duj27us.exe

  Lenovo X220 unable to wlan after resume from sleep

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I just upgraded to Ubuntu 16.04, and now whenever I wake up my laptop
  from sleep (hibernate doesn't work due to encrypted home directory), I
  am unable to connect to any wlan network. After a hot reboot or cold
  start everything is back to normal.

  Network manager would allow me to select already known wlan networks
  through "connect to hidden network", however, it would not allow me to
  establish the actual connection (connect button never becomes active).

  I will attach four files to this bug report:

  1. dmesg-pastreboot: dmesg after a hot reboot
  2. dmesg-pastsleep: dmesg after wakeup from sleep
  3. syslog-pastreboot: syslog snippet from timeframe after reboot
  4. syslog-pastsleep: syslog snippet from timeframe after wakeup from sleep

  Please let me know, if you need any further data or info.

  this is affecting me from 14.04, and new kernel in 16.04 didn't help,

Bug description:
  Here is the problem statement from the Dell team:

  When booting into Ubuntu 14.04.4 with a Broadwell CPU and an Intel
  Quick Assist Card, the memory location that corresponds to ECRC is set
  to 0x01e0, when the BIOS is setting this location 0x00a0 pre-OS boot.
  This causes the card to not function unless we implement the following
  workaround using setpci.

  “setpci –s AA:BB.C 160.w=0”, where AA:BB.C is the PCI Root Path for
  the Intel Quick Assit Card.

  We’ve verified the memory location is correct when booting to other
  OSes, such as RHEL 7.2 and Windows Server 2012 R2.

  If there is any information you can give as to why this may be
  occurring in Ubuntu or where we may start to debug when the memory is
  changed, we would appreciate it.

Re: [Kernel-packages] SPAM-LOW: [Bug 1593477] Re: Direct firmware load fails for bluetooth

[Mike Jones]

Since it is a new laptop, I do not know if it ever worked. But, there
were updates during the first week of use, so it is up to date.

I have tested upstream kernels before, but since this is my everyday
work laptop, and because it has an encrypted partition, I need to review
the changes I made for booting on an encrypted partition, and make sure
I don't accidentally make an un-bootable system. That would be a
disaster for me.

I'll have a look on the weekend. I assume as long as the old image is
not deleted, and as long as I can boot on the install media, I can back
out of trouble. I just need to confirm this.

[Tony Espy]

@Simon

Pretty sure my results reported in comment #11 were using the silo, so
5.37 doesn't resolve the problem.

I just re-tested on arale ( rc-proposed, 350 ) and still see the same
behavior on the initial connect of the headset.  Unfortunately, I can't
seem to get the headset to work at all now with the latest rc-proposed
image.

I'll retry on krillin later today.

Title:
  [Jawbone ERA] HFP features not working with Bluez5 when phone
  initiates connection

Status in Canonical System Image:
  In Progress
Status in bluez package in Ubuntu:
  In Progress

Bug description:
  While debugging some re-factoring work on the ofono upower plugin, I
  noticed that I wasn't able to answer or terminate calls using my
  Jawbone ERA headset.  I bought this headset last year, and although
  it's an older model, it's spec sheet states that it supports HSP 1.1,
  and HFP 1.5.

  I can pair the device with my krillin, and it properly auto connects (
  note, this seems to work better than my iPhone ).   In-call audio
  works for both incoming and outgoing calls, however I get no ringtone
  in the headset and as mentioned above, I can't answer or terminate the
  call.   I've verified on my iPhone6, that the headset works.  In
  addition to a ringtone in the earpiece, the headset also announces the
  incoming phone number.

  From looking at the ofono debug output, I'm never seeing a new HFP
  connection occur.  I noticed as the upower plugin uses a foreach_atom
  (HFP) style call to update the battery indicators on all attached HFP
  devices.

  I've tested this extensively on krillin, running rc-proposed:

  phablet@ubuntu-phablet:~$ system-image-cli -i
  current build number: 205
  device name: krillin
  channel: ubuntu-touch/rc-proposed/bq-aquaris.en
  last update: 2015-12-16 17:53:19
  version version: 205
  version ubuntu: 20151216
  version device: 20151204-2254a36
  version custom: 2015--36-46-vivid

  I've also tested on mako, rc-proposed ( #317 ).

  For reference here's the versions of bluez, ofono, and PulseAudio on
  the device:

  bluez 5.36-0ubuntu2~overlay1
  ofono  1.17.bzr6908+15.04.20151203-0ubuntu1~awe3
  pulseaudio1:6.0-0ubuntu9.11

[Kernel-packages] [Bug 1561301] Re: [SAMSUNG ELECTRONICS CO., LTD. 870Z5E/880Z5E/680Z5E] suspend/resume failure

[petersaints]

I know that the bug has been marked as expired due to 60 days of
activity. But I'd like to add that the current kernel on xenial-proposed
(4.4.0-25.44) has fixed the problem. The one on xenial-updates
(4.4.0-24.43) is still bugged though. So whatever you have done, you
have done it right :) Please don't break it again!

  The latest security patch for  3.19.0 for Ubuntu 14.04 started
  freezing my laptop (Dell Inc. XPS 15 9530). All the patches before
  this one for the kernel 3.19.0 for Ubuntu 14.04 were OK. From log, the
  last message before freezing was "kernel: ...[drm] HPD interrupt storm

  This is the same symptom as described in the bug
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552333, which is
  a bug raised for 4.2 kernel running on Ubuntu 14.04 using the same
  laptop and the same Ubuntu installation as for this bug.

  At the moment I switched back to kernel 3.19.0-51 that does not cause this 
problem, but the possibility that from now on all future security patches for 
3.19.0 might freeze my laptop sounds very bad.

[Kernel-packages] [Bug 1392176] Re: mounts cgroups unconditionally which causes undesired effects with cpu hotplug

[Serge Hallyn]

"LXC cases, like docker and KVM" - did you mean non-lxc cases?

xenial by default should now be using libpam-cgfs, should not be using
cgmanager, and should not be creating cpusets.

  == Comment: #0 - Preeti U. Murthy  - 2014-10-20

  ---Problem Description---
  Systemd mounts cgroups explicitly every boot. Since the user had no say in 
it, undesired consequences are observed in reaction to cpu hotplug operations.  
Here is how.

  Systemd moves the tasks to the cgroup mounted by it. This cgroup 
automatically becomes the child of the root cgroup which is present by default. 
The children cgroups are not expected to remember their configured cpusets 
after hotplug operations in the kernel. Hence when cpus are taken offline and 
brought back online they are no longer used for load balancing of tasks and 
hence remain unused. 
 This is an undesired consequence because the user had not even asked for 
cgroups to be mounted, yet is not able to use the full capacity of the system.

  Only when the user himself creates cgroup hierarchies, should he be
  exposed to the side effects of cpu hotplug on cpusets. Else all online
  cpus must be made available to him which is not happening since
  systemd mounts cgroups on every boot.

  Hence please revert this feature or provide an explaination as to why this is 
being done.

[Kernel-packages] [Bug 1593226] Re: [Acer Aspire ES1-411] Ubuntu freezes occasionally

[Dennis J. Naranjo]

@ Joseph Salisbury:

As expected due to the results during Kernel install, the machine booted
OK but without Wifi. So, it is not possible for me at this time to
perform any further tests with 4.7.0-040700rc1-generic.

Now I'm back to the old 4.4.0-24, and just applied the following
workaround:

==
1. sudo nano /etc/default/grub
2. There is a line in that: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (like 
this), replace with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash 
intel_idle.max_cstate=1"
Save it (CTRL+O)
3. sudo update-grub
4. sudo reboot
==

I'll be back with the results in a couple of day, or maybe sooner if it
freezes again.

  I am running Ubuntu 16.04 and my notebook freezes occasionally. I am
  running Ubuntu on an Acer Aspire ES1-411 (P6B1).

  There's also an identical Bug filled with Acer Aspire ES1-311 and both
  Ubuntu 15.04 & 15.10 by Christian Wansart here:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509723

  I have no clue what causes this, my system just freezes and I can't do
  anything anymore. When it  happens, I have tried the following
  secuence without any luck, I have to power down manually:

  1. ALT + F2, type xkill + ENTER. 
  2. Press Alt+Ctrl+F1.
  3. While holding Alt and the SysReq (Print Screen) keys, type REISUB.

  Last time I was only viewing a Youtube video using Firefox. I checked
  some log files but I couldn't find anything suspicious.

  Any ideas?

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Uqbar]

I added a couple of extra debugging lines in mux.c, recompiled and ran
it.

debug3: link( 
"/tmp/sshcontrol-f1b458a85cd2aa9d5c115abc12afee9f485ad6b0.XSLUj2BsBSDnTkhZ","/tmp/sshcontrol-f1b458a85cd2aa9d5c115abc12afee9f485ad6b0"
 ): 0
debug3: unlink( 
"/tmp/sshcontrol-f1b458a85cd2aa9d5c115abc12afee9f485ad6b0.XSLUj2BsBSDnTkhZ" ): 0

The ": 0" is the value of the int returned by the two calls. They are
successful according to LINK(3POSIX) and UNLINK(3POSIX).

Seth Arnold is right. OpenSSH is doing the things in the right way.

But somehow the kernel (or could it be the libc?) is messing stuff
around with link() and/or unlink().

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Uqbar]

I am not 100% sure it's not the OpenSSH client. These two debug lines
make me think there's something more to check:

debug3: muxserver_listen: temporary control path 
/tmp/sshcontrol-f1b458a85cd2aa9d5c115abc12afee9f485ad6b0.OqWT4bhQP7Hgit3A
debug1: channel 1: new 
[/tmp/sshcontrol-f1b458a85cd2aa9d5c115abc12afee9f485ad6b0]

The former path matches what lsof reports (without arguments), the latter 
matches what the file system does.
At line 1262 the path appendix is created in a for loop.
The expanded path (options.control_path) is then passed to the unix_listener 
function.

That path extension is clearly created by OpenSSH client that way.
But maybe there's something going wrong with the subsequent move, as lsof is 
still reporting that expanded path!

I used kernel 4.4.0-25-generic from xenial-proposed, and was able to perform 
129 iterations of the leaf-eeh tool without crashing. Issue looks fixed with 
that kernel, thanks!
Moving to verified...

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Seth Arnold]

I gave misc.c a quick skim before looking into the kernel:

int
unix_listener(const char *path, int backlog, int unlink_first)
{
struct sockaddr_un sunaddr;
int saved_errno, sock;

memset(, 0, sizeof(sunaddr));
sunaddr.sun_family = AF_UNIX;
if (strlcpy(sunaddr.sun_path, path, sizeof(sunaddr.sun_path)) >= 
sizeof(sunaddr.sun_path)) {
error("%s: \"%s\" too long for Unix domain socket", __func__,
path);
errno = ENAMETOOLONG;
return -1;
}

sock = socket(PF_UNIX, SOCK_STREAM, 0);
...
if (bind(sock, (struct sockaddr *), sizeof(sunaddr)) < 0) {


They memset 0 the struct, and pass the size of the struct. So I suspect OpenSSH 
is fine.

Thanks

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Uqbar]

OK. I did just a bare minimum checks.
The file is called mux.c, the function is "void muxserver_listen(void)" at line 
1241.
Two comments seem quite important:

/*
 * Use a temporary path before listen so we can pseudo-atomically
 * establish the listening socket in its final location to avoid
 * other processes racing in between bind() and listen() and hitting
 * an unready socket.
 */


and 

/* Now atomically "move" the mux socket into position */


Unluckily I haven't enough time to go on. Maybe later...

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Uqbar]

I am not really sure this is not OpenSSH.
The logs above are quoting both socket names. And the name, afaik, is defined 
by the program (openssh-client) not by the kernel.
But I could be badly wrong as I have no time to inspect the software source 
code.

  1. Create a ControlPath socket with something like "-o

  2. Check with ls the socket is there. I am getting

  3. Ask lsof who's that socket belonging to:

  lsof /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705

  4. Ask lsof the same but with grep

  ACTUAL RESULTS.

[Kernel-packages] [Bug 1531768] Re: [arm64] lockups when idle if tickless (nohz=on) is used

[Colin Ian King]

I'd like to factor out if we are missing IRQs on the host and inside the
VM, so can both be booted with kernel parameter: irqpoll

unfortunately this can eat more cpu cycles, so I'm reluctant to ask for
this to be used, but I'm wondering of the host or VM are occasionally
missing timer wakeups

Title:
  Wireless card QCA6164 crashes when booting

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've been trying to get my Qualcomm Atheros QCA6164 (168:0041 rev20)
  to work with diffrent firmwares without success. I've been testing
  Kalle Valos and atondvals firmware with no luck. Kalle Valos firmware
  enables wifi over 2,4GHz only, and not on every router for me. Last
  night I tried the new linux-firmwaren from:

  "http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-
  firmware_1.157_all.deb"

  That didn't work either.

  I did install it, rebooted only to see the WiFi icon flash, so I tried
  "systemctl restart NetworkManager.service" just to see the WiFiicon
  falsh again and then the networkmanager crashed compleatly. so I ran
  the command again to get it back up but still no WiFi.

  Here is the dmesg for the ath10k

Since that didn't work I installed this:

rebooted and the Wifi worked again.

  ControlPath unix socket is created in a weird way

Bug description:
  STEPS.

  1. Create a ControlPath socket with something like "-o 
ControlPath=/tmp/sshcontrol-%C" during an SSH connection.
  2. Check with ls the socket is there. I am getting

  srw--- 1 enzo enzo  0 2016-06-17 10:17:21 sshcontrol-
  369d1187d3900c559f063f947218528001d0e705

  3. Ask lsof who's that socket belonging to:

  lsof /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705

  4. Ask lsof the same but with grep

  lsof | grep /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705

  ACTUAL RESULTS.
  For step no. 3 I am getting nothing (but the WARNING about 
/sys/kernel/debug/tracing)
  For step no. 4 I am getting:

  [enzo@Feynman ~] lsof | grep

  Where you can see clearly that the socket name has a trailing part
  ".NDScoG3mgs0mWc4q".

  EXTRA STEP.
  5. Ask lsof about the socket with the extended name

I can't determine this. I asked Junien on IRC to put it here.

> Also, what is /proc/cmdline on the VM?

Aside from the "nohz=off" it's rather unsurprising:

  BOOT_IMAGE=/boot/vmlinuz-4.2.0-38-generic root=UUID=b98e4d93-8d8f-4349
-a6ce-b5a87cdb2edd ro nohz=off

  1. Create a ControlPath socket with something like "-o

  3. Ask lsof who's that socket belonging to:

  lsof /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705

  4. Ask lsof the same but with grep

[Kernel-packages] [Bug 1593657] Re: ControlPath unix socket is created in a weird way

[Seth Arnold]

Interesting find. This appears to be a kernel issue, the extra chars are
coming from the kernel's /proc/net/unix file.

[Colin Ian King]

I'm trying to get a reliable reproducer on a similarly sized aarch64
host.  Just so that I'm not missing anything, what is the entire command
line being used on the host to run the VM?

Also, what is /proc/cmdline on the VM?

[Kernel-packages] [Bug 1573062] Re: memory_stress_ng failing for IBM Power S812LC(TN71-BP012) for 16.04

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
895a1067d5b83065afbad3bb02c3c464b71f1b3f

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1573062

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

  memory_stress_ng, as part of server certification is failing for IBM
  Power S812LC(TN71-BP012) in bare metal mode. Failing in this case is
  defined by the test locking up the server in an unrecoverable state
  which only a reboot will fix.

  I will be attaching screen and kern logs for the failures and a
  successful run on 14.04 on the same server.

  Release notes:
  Usage of SCSI LUNs on DS8870 Storage server with μCode Bundles 87.51.xx.0 
(LMC 7.7.51.xx) via NPIV enabled zfcp adaptors causes detection issues. LP 
#1567602 In that case do not use NPIV enabled zfcp adaptors.


  
  Scenario:
  Using Installer 432.
  No DASD devices, just two FCP CHPIDs with two LUNs each (configured for 
NPIV), provided via parmfile.
  I expect the installer to probe and detect the LUNs automatically once I 
enable the FCP CHPIDs.

  Repeated five times, I got different results each time. Detected LUNs
  vary between 2 and 4. One time 3 LUNs appear on SCSI1 and one on SCSI2
  which looks especially odd to me.

  Subsequent steps to create partitions and file systems in the
  installer fail.

  Following is one of the five cases with more details:

  Next, the installer warns that no disk drives were detected.

  I checked this on a system (installer 445) with two NPIV enabled FCP
  devices that have 4 LUNS each. I only get the first of four LUNs per
  adaptor:

[Kernel-packages] [Bug 1518457] Re: kswapd0 100% CPU usage

[Rasmus Larsen]

I had this issue too on AWS.

In my case, it was the udev rule for vm-hotadd and the fix as mentioned
previously basically came down to "touch /etc/udev/rules.d/40-vm-
hotadd.rules" which effectively disables the /lib/udev/rules.d/40-vm-
hotadd.rules file (after a reboot).

The udev rule basically seems to only be active for Xen or Hyper-V and
while it seems the Hyper-V stuff was also present in previous versions,
the Xen stuff seems to be introduced in 15.10 or newer.

So if you're seeing this issue on anything running on Xen, including
AWS, try:

touch /etc/udev/rules.d/40-vm-hotadd.rules
reboot

This is probably a bug in Xen or a bug in the kernel.

  kswapd0 100% CPU usage

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  As per bug 721896 and various others:

  I'm on an AWS t2.micro instance (Xeon E5-2670, 991MiB of memory).
  Occasionally (about once a day), kswapd0 falls into a busy loop and
  spins on 100% CPU usage indefinitely. This can be provoked by
  copying/writing large files (e.g. dding a 256MB file), but it happens
  occasionally otherwise. System memory usage (not including
  buffers/caches) currently sits at 36%, which is typical[1]. Initially
  I had no swap space configured; I've since tried enabling a 256MB swap
  file, but the problem continues to occur and no swap space is used.
  The system can be recovered with `echo 1 > /proc/sys/vm/drop_caches`.

  Happy to provide further information/take further debugging actions.

Title:
  Wi-Fi password being ignored in prompt

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When I try to connect to wireless networks, I usually use the GUI in
  the top-right of the screen to select a network. I get a prompt which
  says that to connect I require a password. If I put the network
  password in the textbox and I press Enter (or click on the button) the
  prompt closes but it doesn't connect to the network and the password
  is ignored. I usually have to go in the Wi-Fi settings, select a
  network's settings and put the password in the textbox in the Security
  Tab. When I apply and select the network it connects and all is fine
  from that moment on.
