Hello, In my testing of crosvm[1] with Linux 4.4.175, I am observing failures on a 'kevin' Chromebook (RK3399) device - the guest kernel does not even get to the point of printing its first messages, and the host seems to be spinning at 100% CPU in KVM_RUN. I narrowed this down to the 4.4 stable backport of "arm64: KVM: Skip MMIO insn after emulation" - with this patch reverted, I can boot the g...

KMS drivers really should all be able to restore their display state on resume without fbcon helping out. So make this the default. Since I'm not entirely foolish, make it only a default, which drivers can still override. That way when the inevitable regression report happens I can fix things up with a one-liner plus FIXME comment that someone should fix up the suspend/resume code in that
