--- Comment #3 from Samantha McVey samantham@posteo.net --- X and mesa were not upgraded. It is repeatable, where if I boot into an older kernel things work, and if I boot into the latest Linus master my system will freeze within the next 30mins on average. Firmware is the latest from linux-firmware.git (thus it includes the recent Raven firmware bump).
I will revert that commit and see if I still get the GPU lockup.
