Bug 253801: graphics/drm-fbsd13-kmod panic when resuming from sleep
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253801



--- Description ---
OS: FreeBSD 13.0-BETA3
Graphics: Intel HD Graphics 5500
Driver: modesetting

Sometimes, graphics won't work after waking up from suspend. It shows:
"drmn0: Failed to idle engines, declaring wedged!"
Note this doesn't cause a panic-reboot.

Other times, it seems to resume just fine, but triggers a panic after a few
seconds of use. It either logs me out of my running session, or instantly
reboots my system.

These issues don't happen all the time. Actually, I'm not sure how to
consistently reproduce them :(
But as far as I can tell, it's been happening since at least 13.0-ALPHA3.
