Same problem when doing hibernate, even using 'shutdown' mode.
So no magic missing help from bios on resume of screwup from bios on resume is
expected.

Another sample:

[drm] nouveau 0000:01:00.0: PGRAPH_TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at
07bf00 warp 1, opcode ff1f515e ff1f515e
[drm] nouveau 0000:01:00.0: PGRAPH - TRAP
[drm] nouveau 0000:01:00.0: PGRAPH - ch 4 (0x0001ccd000) subc 5 class 0x8297
mthd 0x1b0c data 0x1000f010

And another:

[drm] nouveau 0000:01:00.0: PGRAPH_TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at
07bf00 warp 12, opcode 00000000 00000000
[drm] nouveau 0000:01:00.0: PGRAPH - TRAP
[drm] nouveau 0000:01:00.0: PGRAPH - ch 4 (0x0001319000) subc 5 class 0x8297
mthd 0x1b0c data 0x1000f010

All errors suggest that always MP1 of TP0 executes random garbage code.
So maybe, maybe......
