Panfrost hanging the system?
Hi folks! kernel 5.8.17 on focal with mesa 21 git-b3504f41 focal-oibaf-ppa I am experiencing some odd hangings last couple days, mostly on firefox. the all system hang. I checked the kernel log and I see this a lot before going down.

could be the cause?? UPDATE: It may not be the cause of the hang, but doesnt look great anyway.
