[Kernel-packages] [Bug 1845046] Re: Bluetooth headphones/speaker default to low quality headset mode and fails to switch to A2DP when selected

[s.illes79]

Same problem with Sony WH-1000XM2

My workaround is

1. Turn on headphone, wait to connect with low quality sink
2. Turn off bluetooth, wait couple of seconds and turn on
3. Reconnect headphones.

Works all the time.

Ubuntu: 18.04
Sony WH-1000XM2

Bug description:
  SRU Justification

  Impact: Many users are reporting issues with bios corruption with
  17.10. This seems to stem from enabling the intel-spi-* drivers in the
  kernel, which don't appear to be ready for use on end-user machines.

  Fix: Disable this driver.

  Test Case: Fix has been verified by our HWE team on affected hardware.

  Regression Potential: Minimal, it's unlikely anyone is actually doing
  anything which requires this driver.

  ---

  Hi all,

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!

   UPDATE (20/12/2017) 

  LENOVO machines affected so far (please add your affected model to
  this list):

  Lenovo B40-70
  Lenovo B50-70
  Lenovo B50-80

  Lenovo Yoga 2 11" - 20332

  Acer TravelMate B113
  Toshiba Satellite S55T-B5233
  Toshiba Satellite L50-B-1R7
  Dell XPS 13 9350 I7.

  Bug may effect machines from any manufacturer that uses BIOS based on
  Insyde Software

  I experience a very poor 802.11ac performance of a QCA6174 Wireless card

  Testing wireless speed with RT-87U 802.11ac router shows that the
  speed is only 27.3 megabits per second which is very low for an
  802.11ac card:

  iperf -c rtr
  
  Client connecting to rtr, TCP port 5001
  TCP window size: 85.0 KByte (default)

  [ ID] Interval   Transfer Bandwidth
  [  3]  0.0-10.0 sec  32.6 MBytes  27.3 Mbits/sec

  

  For comparison, on the same network (from the same distance to the
  router) I have the following result with an Intel's card (on a 4.8
  kernel, different laptop):

  UX32LN:~$ lspci | grep 7260
  02:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)

  200 Mbps is much better.

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[s.illes79]

I've been experimenting with 4.12.3-041203-generic, not crashes but
sometimes the screen goes blank for 3 seconds, from syslog

Jul 27 14:50:45 XPS13 org.gnome.Shell.desktop[1986]:
intel_do_flush_locked failed: Cannot allocate memory

it recovers nicely, no apps gets killed and nothing gets restarted (
other than gnome desktop ??? )

Believe me I already complied there, but nothing happened.

Just had this crash again ( after installing

[s.illes79]

this is ridicules, this bug was reported long time ago (2017-04-07), the
patch was created long time ago and here we go.

I might need to abandon the Ubuntu ship and install openSuse or
something else where bugs get fixed.

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[s.illes79]

just had a crash with 4.12 ... nothing in the log after reboot so cannot
neither confirm nor deny this was the same crash :(

  zesty unable to handle kernel NULL pointer dereference

Bug description:
  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

  Thanks!

[s.illes79]

has this been backported to 4.10 yet?

so far so go 4.10.0-22-generic is. maybe because I stopped using chrome
and use firefox instead?

2 days uptime and no crash

[Kernel-packages] [Bug 1680904] Re: zesty unable to handle kernel NULL pointer dereference

[s.illes79]

With Linux XPS13 4.8.0-46-generic:

09:24:36 up 25 days, 10:33, 10 users,  load average: 3.49, 2.40, 1.91

4.8.X is super stable, this is on a work laptop with high load.

Title:
  zesty unable to handle kernel NULL pointer dereference

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Zesty:
  In Progress

Bug description:
  Upgraded to zesty about a week ago. Ran into this on latest kernel.
  (during high load, nothing in particular seems to cause it to happen).

  Did not happen with previous (4.10.0.14.16) kernel. Only after update
  to 4.10.0.15.17, has happened about 3 times since then (or other
  crashes), this is the one I could capture.

  kern.log entries below. Let me know if you need anything else from me.

  Thanks!

  I dont' have this issue showing in dmesg when using 3.19 kernel,  only
  with later kernels.  Is it related to selecting encrypted home on
  install or something?

   I don't notice any issues with performance because of it or have any
  other error messages.  I am using default ubuntu xenial 16.04 with

  I dont' have this issue showing in dmesg when using 3.19 kernel,  only
  with later kernels.  Is it related to selecting encrypted home on
  install or something?

   I don't notice any issues with performance because of it or have any
  other error messages.  I am using default ubuntu xenial 16.04 with
  unity.

[s.illes79]

Generally I'm having stability issue since
- upgraded to 17.04 - xorg freezes with kernel Ooops
- installed virtualbox - resume fails

I removed virtualbox and suspend seems to be ok
The bug opener also has vbox modules loaded, which makes me wonder if this all 
coz by virtualbox?

anyone else with this problem also have virtualbox installed?
