Beginning a couple of weeks ago, I started to experience occasional freezes or sudden blank screens on my 64-bit jessie system.
It just happened again, and this time the following appeared in the syslog: Jul 17 13:55:05 homebrew kernel: [24064.296254] nouveau E[ PFIFO][0000:01:00.0] write fault at 0x000029d000 [PTE] from GR/GPC0/GPCCS on channel 0x003fbad000 [Xorg[2071]] followed by several more messages that appear to be related, the last of which was: Jul 17 13:58:23 homebrew kernel: [24262.075187] nouveau E[ DRM] GPU lockup - switching to software fbcon I don't know how a particular driver gets chosen by the system, but is there a different driver I could try? Also, is there a way to find out when was the last time that nouveau was updated on my system? If it was a couple of weeks ago, then I would be even more sure that it's the culprit.
