It doesn't fail at the LTR.
Xen resumes back, but dom0 hangs there(technically speaking, it doen't hang, 
eip changes, but can't come back to shell console),
I used xen serial line to dump the dom0 registers,
the eip it runs to from time to time is 'general_protection' in dom0.

Any idea?

Fixing type to 9 doesn't really solves the problem, it has the same phenomenon.
I'll have a double check, and try to dump more registers and variable according 
to Jan's advice and see if 
something un-expected happens.

Thanks.
