Title:
ath9k freezes suspend resume Ubuntu 17.04
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:
Fix Released
Bug description:
[SRU Justification]
[Impact]
Ath9k stops working after system resume from suspend.
[Test Case]
Suspend/resume the system.
Ath9k should no longer freeze.
[Regression Potential]
This patch only effects ath9k, also, the change is pretty small.
The regression potential should be really low.
---
Description: Ubuntu Zesty Zapus
Release: 17.04
What was expected to happen?
I expected the laptop would suspend and resume without issues
What happened instead?
First the network fails, then all other programs slowly start to fail as well
until the system freezes completely. The system is unable to shutdown and it
requires a forced shutdown.
Often when suspending my system, a recent upgrade to 17.04 from 16.10,
after resuming the network does not work and then slowly the whole
system freezes. Looking at dmesg, the problem seems to arise just
before the system suspends with the kernel trace attached below.
My best guess is that the issue is caused by ath9k. My system is a
Dell XPS13 version 9333 (2013) running kernel 4.10.0-22-generic (with
8GB of RAM and no swap) and it is often connected to a Dell U3011
monitor.
I could not find other reports of this bug and this behaviour is new
to 17.04, that is, it was not present in 16.10. I was always able to
suspend and resume without issues before. I have been waiting to see
bug 1674838 fixed before reporting this bug thinking that they might
be related, but they are clearly independent as I am still having this
suspend issue.
Happy to try to collect more info if this information is not enough to
understand where the problem lies, however it is impossible to run
apport once the bug arises.
