Please file a new bug at
https://gitlab.freedesktop.org/drm/intel/issues/new
boot with drm.debug=0xe and attach the resulting dmesg to the bug.
Also include the ouput of these
lspci -vs 0:02.0
lspci -nvs 0:02.0
And I'd like to see a dump of the vbios. Can be done like so:
echo 1 > /sys/devices/pci0000\:00/0000\:00\:02.0/rom
cat /sys/devices/pci0000\:00/0000\:00\:02.0/rom > vbios.dump
Pls attach that to the bug as well.
