When you said "pci=nomsi seems to work" - has the problem got resolved for you using pci-nomsi? I am using Oracle VM 2.2.1 and although we do not see the Mailbox command timeout message, infact we have not got many messages at all in the /var/log/messages - but we have observed IO getting stalled to few or most of our LUNs configured as ocfs2 filesystems. The port do not show as down (from the SAN logs we have checked) and the LUNs getting stalled for a server - there is no problem from other servers to write to that LUNs (as they are shared to other servers being ocfs2). But for some reason - I am getting a feeling that our problem could well be the reason of what you are facing, hence request some feedback from you.
