I have access to a ProLiant BL465c G5, which can boot a xenlinux based dom0 kernel, like the one included in SLE11SP4. But it fails to do that with staging-4.15 and staging:
...

[ 0.197199] node 0 link 2: io port [4000, ffff]

....
I have attached the full logs from staging-4.14 and staging-4.15.

Can you boot with dom0=msr-relaxed on the Xen command line?

Yes, that helps - I just discovered this cmdline option.
