[Po-Hsu Lin (cypressyew)]

From the test history, this P8 node was tested with 4.15.0-21, which
mean that the deployment works with some version earlier than
4.15.0-21, and at least it can boot with 4.15.0-21 in the last cycle.

So it's a bit odd to me to see the deployment failure here, as it should
be deployed with working 4.15.0-21 from the last cycle.

And it's not the 4.15.0-23 in -proposed that's causing this this problem, the system was never boot with 4.15.0-21.

Manually overriding after checking the outstanding bugs.

[Stefan Bader (smb)]

Looks like the P8 problem is one introduced in the 4.15.0-22 release (which was the security update related to spectre v4). There is a fix pending for that and will be included in the next cycle. So given this is not a regression introduced by the kernel from this current cycle, I would switch regression testing to good and we need to make sure to verify that the next cycles kernel does work on P8 (maybe deploy xenial and replace kernel).
