It seems 5.0.13 works but 5.0.21 do not.
Comment 3 Jani Saarinen 2019-08-14 06:58:36 UTC
Actually I had accidentally one extra command line parameter i915.enable_guc=1 too.
It seems with that system do not boot to Desktop. This also with .13.

Added those log again (un-obsoleted)
Comment 5 Chris Wilson 2019-08-14 08:31:50 UTC
Probably a bit late now to fix; everyone who tried 5.0 with an unsupported option will have already given up (either on the enable_guc, 5.0 or us).
