Re: kern/55667 (regression: XEN3_DOM0 fails to boot on)

OK, I got some test results:

    1) console=pc get a black screen after xen boot output when the 
kernel starts - regression probably to new drm code

    2) boot with SOL on com2 show a quick boot, xen domains start, nvme 
disks seem to work - good

    3) Networking sporadically 'works'

ssh logins work, but have long delays (see pings).

shutting down the first xen domain made the SOL link unresponsive.

shutdown takes forever.

So in summary - console screen broken, networking broken, basic xen 
seems to work again but

the machine is still unusable - probably still issues with interrupts on 
network (and possible other) devices.

Thanks for the partial progress here.
