Occasionally, when switching any video playback into full-screen, all system video, except for the mouse pointer, hangs until reboot. It is possible to SSH into the machine for a while until it freezes completely. Video card: NVIDIA Corporation GK104M [GeForce GTX 670MX] (rev a1) Operating system: Archlinux with linux 3.19.3-3-ARCH nouveau-fw is installed and nouveau.config=NvGrUseFW=1 is in the kernel parameters. I logged in via SSH into the blocked machine and dumped dmesg's output, it produced a 6MiB sized file of only: [ 432.267634] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267645] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267647] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267658] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267661] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267672] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267674] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267685] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267687] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267698] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267701] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267712] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267714] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267725] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267727] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267738] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267741] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267752] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267754] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267765] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD [ 432.267767] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 6 [gstglcontext[1984]] subc 0 mthd 0x000c data 0x2001054e [ 432.267777] systemd-journald[276]: /dev/kmsg buffer overrun, some messages lost.
You shouldn't need to use blob context switching firmware... I'd start by removing nouveau.config=NvGrUseFW=1 Also, if this is recent, and you're using libdrm-2.4.60, try downgrading to libdrm-2.4.59.

Effectively this is recent, I downgraded to libdrm-2.4.59 and removed the kernel parameter. I still could reproduce the issue with a secondary screen and with the primary only, It tried that because I though it could be because of the secondary display. relevant output of dmesg when reproducing with two displays: [ 195.394185] compiz[1209]: segfault at 7f23ad5c7580 ip 00007f23ad5c7580 sp 00007ffec56131a8 error 14 in card0[7f23ad7cd000+200000] [ 518.479158] gstglcontext[2295]: segfault at 8 ip 00007f5d39a4272e sp 00007f5b9bffe950 error 4 in libdrm_nouveau.so.2.0.0[7f5d39a3f000+6000] [ 586.592466] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: PBENTRY [ 586.592475] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 10 [gstglcontext[3129]] subc 0 mthd 0x0000 data 0x00000000 relevant output of dmesg when reproducing with a single display: [ 376.359606] nouveau E[ PFIFO][0000:01:00.0] read fault at 0x01b3f00000 [UNSUPPORTED_KIND] from CE2/GR_COPY on channel 0x00bf449000 [unknown]
