--- Comment #10 from Frédéric Pierret (frederic.epitre@orange.fr) --- Last piece of information, aach time I'm trying to reproduce the freeze and thanks to the fix, I can see a second information in kernel log:
[ 814.207723] nouveau 0000:26:00.0: disp: chid 73 stat 00001080 reason 1 [PUSHBUFFER_ERR] mthd 0200 data badf5040 code badf5040 [ 814.207749] nouveau 0000:26:00.0: bus: MMIO read of 00000000 FAULT at 611390 [ IBUS ]
And it's always repeated as the two lines.
