dmesg output
Hi, I have tested this several times with several different kernels, always
with the same result. It deadlocks wayland or X within seconds after opening a
terminal or chrome.
It starts out like this:
[ 108.167312] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[ 108.167328] nouveau 0000:01:00.0: fifo: msppp engine fault on channel 12,
recovering...
[ 118.871915] nouveau 0000:01:00.0: multiqueue0:src[7039]: failed to idle
channel 12 [multiqueue0:src[7039]]
[ 133.873009] nouveau 0000:01:00.0: multiqueue0:src[7039]: failed to idle
channel 12 [multiqueue0:src[7039]]
[ 134.242698] nouveau 0000:01:00.0: mspdec: intr 028c0000
[ 134.242744] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 084048
[ IBUS ]
[ 138.538241] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[ 138.538259] nouveau 0000:01:00.0: fifo: mspdec engine fault on channel 12,
recovering...
[ 140.537498] nouveau 0000:01:00.0: fifo: runlist update timeout
And then it all breaks down and never recovers (the machine is reachable but
can't reboot properly afterwards)
