The kernel is built from konrad's tree, devel/next-2.6.39
commit:f4ddaaf4338999227b3f724615d8aecbe88d3f04
64 bit PV guest, 64 bit dom0, xen 4.1.0-rc7-pre
I have not been able to boot a pv domU, with the above kernel.
xl debug shows:

You might need this git commit:
31fd38842ab07b95440f24c6180d9a2c14b35111
tc/cmos: Check if ACPI is disabled, and if so don't attempt
If you pull my tree, you should be able to cherrypick.

Ok. So you got Stefano's latest goodies:
* devel/bootup-fixes.v3:
watchdog, SP5100: Check if firmware has set correct value in tcobase.
xen: update mask_rw_pte after kernel page tables init changes
xen: set max_pfn_mapped to the last pfn mapped
x86: Cleanup highmap after brk is concluded

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

Also do 'earlyprintk=xenboot' in your PV guest and see what it tells you
(if anything).

no. dom0 is 2.6.32.27 (from xenbits pvops tree).

FYI, this throws a warning
linux-2.6/drivers/rtc/rtc-cmos.c:1000: warning: ‘return’ with no value, in

And you are using 'xm' or 'xl'? Try the either one just to make sure it is
not something silly there.

Tried both. Same issue.
Btw, if you have a working domU, can you please test Rafael's patch for the HIBERNATE_INTERFACE ? he replied to my
"PATCH v3 3/5 Add visible HIBERNATION_INTERFACE and hide HIBERNATION" with his version of the refactoring patch.
I can compile the code but am not able to test it due to this boot issue. And before you ask, yes, all bugs reported here were without his patch.
If it works out okay, we might be able to push the remaining 3 bits of the freeze-thaw patch via his tree, hopefully.

Will try this week . Do you have a branch on which you put all of the patches that you were trying to test?

This branch tracks your devel/next-2.6.39
I have committed both patches (hibernate_interface and the xen config fixes)
into that branch. I
didnt commit the rtc/cmos bug fix as it didnt seem to help.
