The tree seems to be dirty, what changes have you made into Xen?

Hmmm... have seen a such error yesterday on one of my platform and was 
not able to reproduce afterward :/.
IIRC the PC was pointing to arch/arm/mm.c:1098. Can you confirm it is 
the same for you? You can use addr2line here.
Can you reproduce it reliably? If so, could you provide your xen config, 
linux config, linux tree you are using?
Regards,
