I had this issue a month or so back, upgraded to 5.11 and it was fixed. After an update yesterday this error is back in full effect, now on Kernel 5.12. The error is the exact same as always:
Downgrading Mesa to 21.1.4 did NOT fix the problem as I initially thought, and the crashing persists after the downgrade too. I don’t know what to do to solve this issue currently, and it appears the error is closely linked to Steam’s usage of mesa. Any ideas?
Edit: The other thread on this issue recommends downgrading linux-firmware. Linux firmware is already downgraded from the last time I attempted to fix this and is exempt from being updated, but I’ll try fickling with it and see if the crashes cease.
