Last modified: 2018-03-15 01:37:39 EDT
Description of problem:
Machine randomly hard locks, mouse / keyboard inputs no longer work (Unable to switch VTs, etc). Hard reset is only way to recover.
Version-Release number of selected component (if applicable):
Random, could happen within 15 minutes of boot or 10 hours; however, seems to happen most when in a browser, Chrome / Firefox.
Steps to Reproduce:
1. Browse the web with chrome / firefox
Machine hard locks and only recoverable via a hard reset
Just before the lock, the following is output in /var/log/messages:
kernel: nouveau 0000:02:00.0: gr: TRAP ch 2 [003fa79000 X]
kernel: nouveau 0000:02:00.0: gr: GPC0/TPC0/MP trap: global 00000000  warp 3f0009 [ILLEGAL_INSTR_ENCODING]
Switching to proprietary nvidia driver resolves the issue
I'm getting this super frequently as well (2-10 times per day!). I'd switch to the proprietary nvidia (which fixes it for me as well) but then gnome doesn't know how to handle driving 3 video cards with windows. The nvidia driver makes them available (I mouse over and the old X11 disabled screen pointer) but gnome seems to refuse to put windows on them.
