Hi,

we use xen from source and are not able to boot our Ubuntu-DomUs with
kernel 4.15.0-50 in PVH-Mode. In PV-Mode they start without problems.

We activated logging, see the log attached.

The boot stops at;
BUG: unable to handle kernel NULL pointer dereference at 0000000000000000
[...]
Kernel panic - not syncing: Attempted to kill the idle task!


We use the current staging-version with last commit
2a556b63a22dd68697feb3994e68de939d01a804 (before we tried staging-4.12
with last commit 4ed6c8b95c80a6fdc33fab38d3fdae64b8827916).

Are you working on this issue? With staging the boot freezes, with
staging-4.12 the DomU crashed.
We tried with Dom0-Kernel-versions 4.15.0-50 and 4.15.0-48.

Thank you and best regards,
Kelly.
