There were several bugs in the AMD microcode loader, which were fixed (AFAIK, anyway) on later kernel stable updates from kernel.org. They could easily explain the boot failure with the low-latency kernel.

I am not sure if these fixes were incorporated on Ubuntu's 15.10 kernel updates or not. I am also not sure if the low-latency kernel changes to fundamental kernel structures is compatible with the early AMD microcode loader or not.

Is anyone still affected by this bug on *up-to-date* Ubuntu 15.10 with the normal kernel? With an up-to-date low-latency kernel?
