I had three GPU lockups during the last 30min. The first occured while browsing the internet with Firefox, the second one happened during video playback with KPlayer and the last one happened, when I tried to re-compiled my kernel (3.17.4) with nvidia fw included. There was only a X terminal running that showed the build output when nouveau crashed. So yes, the bug still exists in 3.17.4. This is my dmesg output in reverse order: Dec 01 21:10:22 matthias-pc kernel: nouveau E[ PFIFO][0000:01:00.0] read fault at 0x0000013000 [PTE] from PBDMA0/HOST_CPU on channel 0x023f7b0000 [unknown] Dec 01 21:10:22 matthias-pc kernel: nouveau E[kwin[571]] failed to idle channel 0xcccc0000 [kwin[571]] Dec 01 21:10:07 matthias-pc kernel: nouveau E[kwin[571]] failed to idle channel 0xcccc0000 [kwin[571]] Dec 01 21:09:52 matthias-pc org.kde.kuiserver[477]: kuiserver: Fatal IO error: client killed Dec 01 21:09:52 matthias-pc kdm[351]: X server for display :0 terminated unexpectedly Dec 01 21:09:52 matthias-pc kernel: nouveau E[ X[354]] failed to idle channel 0xcccc0000 [X[354]] Dec 01 21:09:37 matthias-pc kernel: nouveau E[ X[354]] failed to idle channel 0xcccc0000 [X[354]] Dec 01 21:09:22 matthias-pc kernel: nouveau E[ DRM] GPU lockup - switching to software fbcon Dec 01 21:07:40 matthias-pc kernel: nouveau E[ PIBUS][0000:01:00.0] GPC0: 0x504610 0x00000402 (0x0502020b) Dec 01 21:07:40 matthias-pc kernel: nouveau E[ PFIFO][0000:01:00.0] PGRAPH engine fault on channel 2, recovering...
