Description Kamil Paral 2015-08-05 07:09:40 UTC 
Hello,

I've experienced a kernel panic, the screenshots are here:
https://bugs.freedesktop.org/attachment.cgi?id=117026
https://bugs.freedesktop.org/attachment.cgi?id=117027

It happened with kernel-4.0.7-300.fc22.x86_64 on Fedora 22.

Originally I reported it against the radeon driver [1], but I was told that it 
seems to be a deadlock in on_each_cpu/smp_call_function_many (which seems 
to be in smp.c) and that I should report it into an appropriate mailing list. I did that [2], but no one replied in two weeks. I hope I picked the right component here in bugzilla.
