Can you please attach the full output of dmesg from this kernel?
Created attachment 1113993 [details] dmesg as requested Thought it was sufficient and preferred to only have the ------------[ cut here ]------------ ---[ end trace..]--- content on reports.

Guðmundsson from comment #2) > Created attachment 1113993 [details] > dmesg as requested Thank you. > Thought it was sufficient and preferred to only have the > ------------[ cut here ]------------ > ---[ end trace..]--- > > content on reports. Generally, no. It just marks the start and the end of the trace information itself. The dmesg often contains much more context. In this specific case, the dmesg provides enough context to show that the first backtrace is almost certainly a duplicate of bug 1083853 for which I am working on a fix today.
I've included the fix for bug 1083853 in rawhide in Fedora git. It will be in whatever build comes out next. The second backtrace probably needs something else.
This bug looks like it has a fix. The 2nd issue comes up from time to time but I think it makes sense to close this one.
