--- Comment #11 from Michel Dänzer (michel@daenzer.net) --- Other Raven Ridge users have reported that updating to the current microcode files from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/... has fixed stability issues.
Make sure your system BIOS and CPU microcode are up to date as well.
