System log file when resuming from power save failed
A system log file as dmesg had wrapped over due to repeating error messages (trimmed from the end of log file as were identical)
After kernel upgrade to 3.11.1 and xorg-server-1.14.3, resume from suspend was still broken but I didn't observe any hangs during power save mode. This issue can be completely fixed by adding Option "NoAccel" "true" to xorg.conf file. Suspend/resume seems to work flawles without acceleration. It fixed also some random hangs during normal work (no bug report as no idea how to triger them or anything in system logs). Leaving this bug open suspend/resume should work also with enabled acceleration. Is this still an issue with more recent kernels? I managed to suspend/resume without any problems with enabled acceleration for some 5 times. Yahoo! Issue seems to be solved. Finally I will get acceleration back (and thus upgrade to xf86-video-nouveau-1.0.11 #86164). Tested with: kernel: 4.2.4-gentoo xorg-server-1.17.4 xf86-video-nouveau-1.0.10-r1 |

Created attachment 85873 [details] Xorg log file when X failed to recover from power save state When resuming from suspend to ram or blank screen (power saving), mouse is working but screen is stuck (not garbage). After SSHing into system, it was under high load as X and kworker processes where fighting for CPU. dmesg was full with "nouveau E[ X[2406]] nv50cal_space: -16" Reboot fixes the issue. Gentoo ~AMD64
