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).
