OK. After making kernel handle the TP1 error bit, the error was decoded, and
tried several times. These are errors we got:

1st try:

[drm] nouveau 0000:01:00.0: PGRAPH_TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at
07bf00 warp 9, opcode ffc8c2bf ffc8c2bf

2nd try:

[drm] nouveau 0000:01:00.0: PGRAPH_TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at
07bf00 warp 1, opcode ff1f515e ff1f515e

3rd try:

[drm] nouveau 0000:01:00.0: PGRAPH_TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at

It was also found that 2d usage after resume from ram and/or xvideo playback
don't trigger that MP fault.

Also following suggestions from Marcin Slusarz were tried:


We tried to restart X after resume from ram, and once again no errors.
We tried running rendercheck -tblend, just 9 out of 18 tests passed, but no TP
error.

Its somewhat strange as if nouveau drm module didn't restore some of TP/MP
state, the error should have being triggered by X as it does use shaders that
have to choice but to run on MP/TPs.

Also running just glxinfo was attempted. That does all the 3d init but doesn't
render anything (I checked this). No errors.

Thats is ***ing strange, that all I can say, and I am out of ideas for now.
