Bug Description
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/
/var/log/
/var/log/
/var/log/
/var/log/
02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)
Any help appreciated.
Thanks,
Bruce

I don't easily see the firmware hang message in the attached files, so I'm pasting it here:
