Thanks for your > work on the linux > kernel and the respective documentation 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. -- Ville Syrjälä Intel _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
