Heya,
I am hitting _three_ different regressions on v3.9-rc0. I was
wondering if anybody is willing to help me out in narrowing down
the faulty git commits.
The first one is when booting PV guests:

And the third when booting dom0 and with xen-acpi-processor it ends
up with -22 right after:

The bug here quite obviously is that with no ACPI you shouldn't
even get to that point. Yet apei_hest_parse() blindly uses
hest_tab - that ought to regress on real hardware too.
