Hi, When it is shutting down a Windows XP guest that has been passed through HD Audio Controller of ICH9 by VT-d, there is a problem that the following message is repeated many times in hypervisor''s log and the shutdown''s process does not end. (XEN) mm.c:661:d1 Bad L1 flags 10 Attached patch fixes this problem.
