[Bug 287389] graphics/drm-61-kmod: GPU hang

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287389

--- Comment #4 from Pero Oršolić <[email protected]> ---
Reproduced it minutes fresh after reboot with drm-515-kmod-5.15.160.1403000_6
Music in Firefox will play some 30 seconds and then stop.
mpv process is now in "I" state.

Tried to reproduce it again after reboot and physical power cycle of the PC
with drm-515 without success.
Is there something I can do, some logs to collect? Usage of this PC is less
than ideal.
