Comment # 3 on bug 108606 from Samantha McVey

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.
