I've seen both of these on skylake with kernel 5.4.2, and the GPU hang has reports of kabylake also affected. I imagine those are pretty common hardware. Both bug reports include upstream reference. WARNING: CPU: 2 PID: 1 at kernel/trace/trace.c:8106 create_trace_option_files+0x1ef/0x220 https://bugzilla.redhat.com/show_bug.cgi?id=1781288 [drm:gen8_reset_engines [i915]] *ERROR* rcs0 reset request timed out https://bugzilla.redhat.com/show_bug.cgi?id=1780800 The second is pretty bad in that it appears as a total lockup, locally. Usually I've been able to ssh into the system, but I'd guess most users will just force a power off and start over. -- Chris Murphy _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx
