Created attachment 141754 [details] journalctl --system This is similar but not quite the same bug as #107829 I recently updated arch linux and attempted to use the nouvea driver with my GTX 660 GPU. System will reliable crash after about 30 seconds to 1 min in KDE plasma with the following kernel message. Sep 25 21:18:49 sokka kernel: nouveau 0000:01:00.0: gr: TRAP ch 2 [023fe33000 Xorg[406]] Sep 25 21:18:55 sokka kernel: nouveau 0000:01:00.0: gr: GPC1/TPC1/MP trap: global 00000000 [] warp 3d0009 [ILLEGAL_INSTR_ENCODING] Sep 25 21:19:16 sokka kernel: input input6: event field not found Sep 25 21:19:16 sokka kernel: input input6: event field not found Sep 25 21:19:16 sokka kernel: input input6: event field not found Sep 25 21:19:16 sokka kernel: input input6: event field not found Sep 25 21:21:35 sokka kernel: sysrq: SysRq : This sysrq operation is disabled.

A number of GTX 660 users have a variety of issues with nouveau. Can you see if using blob grctx firmware helps? Follow the instructions at https://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware [make sure you use 325.15 and not another version] This should get you the appropriate grctx firmware. You can then make use of it by booting with nouveau.config=NvGrUseFW=1 (Make sure that the firmware ends up whereever the nouveau module is... if it's loaded from initrd, then it should be in initrd, etc.)
