Comment 2 Chris Wilson 2019-09-16 12:35:04 UTC 
It's not clear what's going on here. As even though we have the beginning of the trace output, we don't have the oops that triggered it. I guess that means it is one of the selftests GEM_TRACE_DUMP (but those I thought had some pr_err before). Still, the output is lost before we complete the dumping and we have no pertinent debug messages. Not even an oops from pstore.

Comment 4 Francesco Balestrieri 2019-10-10 06:28:02 UTC 
Seems to be happening quite frequently though. Does the latest occurrence reveal anything new?

Comment 5 Chris Wilson 2019-10-10 12:35:15 UTC 
The dmesg is still incomplete -- we miss the sequence of operations that lead up to the bug, so we don't have a clear view of what the HW was doing at that time.
