Works again, thanks.

These lines are still there tough:

(XEN) (file=[...]/mm.h, line=187) Error pfn 100: rd=ff19d080, od=00000000, caf=00000000, taf=00000000

Any idea what this is?

Something is trying to map the page at 1MB -- probably some user-space table-scanning program (for example, I know some versions of dmidecode run past the 1MB boundary).

Actually, if your machine is non-ACPI then it is probably the kernel's ACPI code. That has had a bug for ages where it ought to scan 0xE0000-0xFFFFF, but actually scans 1MB from 0xE0000. That would get you the error you're seeing. :-) I submitted a patch once...
