Title:
Desktop system won't run with latest kernel 4.13 36/40
Status in linux package in Ubuntu:
Incomplete
Bug description:
My Intel-based desktop system was working fine with Ubuntu 16.04.3 and
Linux 4.13 32/35 up to 12 Feb 18. Since then it has been unable to
complete a boot-up, and will only run in recovery-mode. I have found
similar symptoms as were previously raised in bug 1568211. These are
the boot messages:
:~$ sudo dmesg | egrep 'drm|radeon'
[ 1.803359] [drm] VGACON disable radeon kernel modesetting.
[ 1.803429] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon
module!
