https://bugs.freedesktop.org/show_bug.cgi?id=80419 --- Comment #58 from David Beswick --- I didn't think to try replaying the trace as I assumed it would have the necessary data in it, apologies. I've done so now, but the system didn't hang. Is it possible that the last part of the trace never makes it into the file because the system locks up? If I switch to another TTY I do see "ring 0 stalled" as in the syslog excerpt attached to the bug. Anything else besides Alt+PrtSqn+REISUB that may help to capture the problematic part? Otherwise, I'll continue gathering traces and will let you know if I get one that a replay can trigger. -- You are receiving this mail because: You are the assignee for the bug.
