These two I've never seen before: nouveau 0000:07:00.0: fifo: fault 01 [WRITE] at 0000000000150000 engine 05 [BAR2] client 08 [HUB/HOST_CPU_NB] reason 02 [PTE] on channel -1 [007fd38000 unknown] nouveau 0000:07:00.0: fifo: fault 01 [WRITE] at 0000000000000000 engine 05 [BAR2] client 08 [HUB/HOST_CPU_NB] reason 0a [UNSUPPORTED_APERTURE] on channel -1 [007fd38000 unknown] And the SCHED thing is most frequently due to the ctxsw firmware timing out or other error. But given the faults above, could easily be follow-on from that. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 3+ messages in thread

For me - I am using Ubuntu 16.04 with nvidia blob on this laptop. But when trying different ubuntu versions, I always get this spamming in system logs. (the laptop is HP ENVY 15-j192nf - K4D07EAR#ABF) For the actual bug - how can this issue be further diagnosed?
