Public bug reported:
Lately my notebook has been doing a watchdog reset effectively killing the
desktop session and brutally landing in a busybox session.
These are usually the last lines in kern.log when that happens:
Mar 28 21:50:35 taco kernel: [ 174.090910] wl0: PSM microcode watchdog fired
at 146 (seconds). Resetting.
Mar 28 21:50:35 taco kernel: [ 174.090914] wlc_dpc : PSM Watchdog, chipid
0xa8d9, chiprev 0x1
Sometimes the system does some more logging before the kernel dies but
most often not.
