Hello,

We found that our HVM guests froze when trying to emulate movntq
instructions. The solution seems to be to replace "goto done;" with
"break;" at line 4191 (when handling "case 0x7f:") in
xen/arch/x86/x86_emulate/x86_emulate.c. Otherwise the writeback part
doesn't happen.

If you're happy with the fix I can prepare a patch, otherwise please let
me know if we're missing something.


Thanks,
Razvan Cojocaru
