description |
My system freezes and reboots 30 seconds later. This happens at random times between shortly after boot or up to three ours after boot. My CPU is a Core i5 5675C. I think it is the same problem discussed here https://bugzilla.kernel.org/show_bug.cgi?id=103351
They have a microcode update as a fix there.
All Broadwell CPUs seem to be affected. It does not happen with Fedora 22.
There are two workarounds that help for some people:
1. boot with "processor.max_cstate=0 intel_idle.max_cstate=0 idle=poll"
2. Disable speedstep in the bios
Both don't work for me. |
