Bug description:
My system keeps freezing on a brand new install of Kubuntu 18.10,
always with the kern.log error "[drm:intel_pipe_update_end [i915]]
*ERROR* Atomic update failure on pipe A (start=4120234 end=4120235)

I think it's probably a duplicate of these bugs which were closed unresolved:
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1660619 (closed as it was
on an older version of Ubuntu)
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1671975 (closed because
it was a duplicate of the first bug)
It happens far more frequently if I have desktop effects turned on,
and far less frequently when using a live USB key (at always happens
eventually though. Usually once every few hours.)
Please advise how I can help triage / test. My system is a new install
now, so I'm perfectly willing to modify / reinstall to help testing
(I've reinstalled 5 times to test things, but never managed to find a
solution)
