text/plain snippet of /var/log/messages
The relevant parts of /var/log/messages were too big to attach uncompressed,
but they appear to consist of repeated sections like this.
The machine was completely hung after this point, but did respond to Magic SysRq requests. The two blank monitors were DP-1 and DP-2. The log output was visible on DP-3 and DP-4. Those errors are most likely to happen when e.g. you're accessing a UBO out of its bounds. Or if the driver messed up binding said UBO... or some code generation error. However it should be ~harmless, except for the fact that the render in question will be messed up. BTW, what mesa version are you using? The DISP errors at the end are the reason (or at least a demonstration) that the GPU hung. I suspect the rest of the system was totally fine. This also looks worrying: [160330.118473] nouveau E[ PFIFO][0000:01:00.0] write fault at 0x00004d6000 [PTE] from GR/GPC0/PROP_0 on channel 0x007f971000 [Xorg[981]] [160330.118474] nouveau E[ PFIFO][0000:01:00.0] PGRAPH engine fault on channel 2, recovering... I'm guessing the errors stressed the ctxsw logic and it couldn't handle some condition. localhost:~# rpm -qa | fgrep mesa mesa-libGL-10.1.5-1.20140607.fc20.i686 mesa-libglapi-10.1.5-1.20140607.fc20.x86_64 mesa-filesystem-10.1.5-1.20140607.fc20.x86_64 mesa-libglapi-10.1.5-1.20140607.fc20.i686 mesa-libGLU-9.0.0-5.fc20.x86_64 mesa-libgbm-10.1.5-1.20140607.fc20.x86_64 mesa-libwayland-egl-10.1.5-1.20140607.fc20.x86_64 mesa-dri-drivers-10.1.5-1.20140607.fc20.x86_64 mesa-libEGL-10.1.5-1.20140607.fc20.x86_64 mesa-libxatracker-10.1.5-1.20140607.fc20.x86_64 mesa-libGL-10.1.5-1.20140607.fc20.x86_64 This has been happening to me for a while, now it is more frequent, it happens even twice a day.

Created attachment 102212 [details] Screenshot of log output I came in to work this morning, to find two of my four monitors blank, and the other two showing the attached log output (screenshot only, because I can't find it in anywhere on the filesystem). /var/log/messages contains errors of the form: nouveau E[ PGRAPH][0000:01:00.0] TRAP ch 7 [0x007f730000 cubicgrid[18458]] nouveau E[ PGRAPH][0000:01:00.0] GPC0/TPC0/MP trap: MULTIPLE_WARP_ERRORS MEM_OUT_OF_BOUNDS cubicgrid is my screensaver (part of xscreensaver) Here's some more information that may or may not be useful.
