Crash in drm_atomic_handler.c #115

Closed arrowd closed 5 years ago

arrowd commented 5 years ago

I'm running 13-CURRENT with drm-current-kmod-4.16.g20181210. Under heavy load (running poudrire build for lang/ghc for instance, I get a kernel panic: http://arrowd.name/drm_crash.jpg

valpackett commented 5 years ago

can confirm, started occasionally getting these panics recently

Looks like you're running out of memory? We haven't really tested OOM situations in the drm drivers so it might be that it doesn't handle it correctly...

I've been running poudriere from console, without running X, and eventually got another panic: http://arrowd.name/drm_crash2.jpg

The backtrace looks the same, and there is the same freeing free block message. It seems the bug is not DRM related?

Upgrading to recent kernel seems to have fixed the problem for me.
