Recent pvops dom0 kernels fail to boot on this particular ProLiant BL465c G5 box.
It happens to work with every Xen and a 4.4 based sle12sp3 kernel, but fails with every Xen and a 4.12 based sle12sp4 (and every newer) kernel.

Any idea what is going on?

I can probably cycle through all kernels between 4.4 and 4.12 to see where it broke.
