Ok. So you got Stefano's latest goodies:

* devel/bootup-fixes.v3:
=A0 =A0 =A0watchdog, SP5100: Check if firmware has set correct value in tc= obase.
=A0 =A0 =A0xen: update mask_rw_pte after kernel page tables init changes =A0 =A0 =A0xen: set max_pfn_mapped to the last pfn mapped

Is the 64-bit dom0 kernel =3D=3D 64-bit domu kernel?

FYI, thi= s throws a warning
linux-2.6/drivers/rtc/rtc-cmos.c:1000: warning: =91return=92 with no value,= in function returning non-void
=A0
Also do 'earlyprintk=3Dxenboot' in your PV guest and see what= it tells you

No extra messages in xen's log.
