Thanks for your report.

Could you run the following command as root, and paste the output, if any?
> /usr/bin/pkla-check-authorization gdm true true org.freedesktop.RealtimeKit1.ac
(without the starting '>' character)

Hello.
I would like to help but I've already formatted my computer and I'm no longer using Fedora.
I've been thinking about those errors and I think they were due to the fact that I overclocked my CPU from the default 3.00 GHz to 3.6 GHz. I did raise the memory timings on the BIOS but I think that it wasn't enough. I think those errors were caused by RAM memory errors due to the overclocking.

Thank you.

Thanks for the information.

The backtrace does support the hypothesis that this is a hardware bug caused by overclocking (%rip points into a middle of an instruction), closing.
