linux: 4.15.0-23.25 -proposed tracker

Hardware Certification have begun testing this -proposed kernel.

Hardware Certification have completed testing this -proposed kernel. No regressions were observed, results are available here: http://people.canonical.com/~hwcert/sru-testing/bionic/4.15.0-23.25/bionic-proposed-published.html

Marking this task as "Incomplete" for bug 1775855, note that ppc64le deployment works for P9, just not for P8

4.15.0-23.25 - generic
Regression test CMPL, RTB.

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.

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).

This bug was fixed in the package linux - 4.15.0-23.25
