[Xen-devel] [BUG] Frozen start screen dom0 with Xen 4.9 - i915 intel HD630

[Xensemann <xensemann@xxxxxx>]

There is an issue with intel HD Graphics 630 and Xen 4.9.
This is affecting xen 4.9 from ppa with Ubuntu 17.10 and a self compiled
version of xen 4.9 with ubuntu 16.04. It looks like the intel driver
i915 is also playing a role.

The behaviour is, that the system is booting but showing a frozen start
screen.

in dmesg ist showing up the following message:
[time] [drm:gen8_irq_handler [i915]] *ERROR* Fault errors on pipe A:
0x00000080
... and lots of more.

The bug is described here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1735383 in detail.

Has someone experienced the same behaviour?
