Public bug reported:
Since upgrading to Kubuntu 17.10 my HP EliteBook 820 G3 hangs at
unpredictable times. I have experienced probably 20 hangs. Once the
system is hung no mouse movement, NumLock toggle, VT switch,
Ctrl+Alt+Del, SysRq keys, SSH attempts have any effect whatsoever. Any
audio playing is stuck looping in the hardware buffer. The system is
really stuck. Only the keyboard backlight is still responsive.
The only correlation I have noticed is that the system only hangs if
WiFi is enabled. This morning I experienced two hangs in ten minutes
necessitating reboots. Having disabled WiFi the system has been stable
since ~1100 (~5 hours).
Often, I see a iwlwifi hardware reset in the logs before the system
dies:
/var/log/syslog:Oct 30 11:49:30 fry kernel: [ 6529.550751] iwlwifi
0000:02:00.0: Microcode SW error detected. Restarting 0x82000000.
(apport has hopefully uploaded the full log, please lmk if not).
Sometimes the message doesn't make it into the logs, and ext4 truncates
the file at the next mount.
There seems to be no correlation with any messages immediately before
the wifi chip dies. It doesn't seem to matter whether I'm at home or at
work. I have wired ethernet at work simultaneously with wifi, but the
wifi provides IPv6 so I would imagine most traffic uses wifi, so it's
hard to say whether there's any effect of the traffic load on the
probability of failure.
Here is a sample of the firmware load:
/var/log/syslog.5.gz:Oct 24 15:37:26 fry kernel: [ 7.604743] iwlwifi
0000:02:00.0: enabling device (0000 -> 0002)

Any help appreciated.
