Re: port-xen/47057: Xen NetBSD DomU file system trash under Linux Dom0

I think I've found the problem, it seems to be related to
xengnt_more_entries, but still haven't been able to point exactly when
the overwrite of xenstore_interface happens. Just after the call to
xengnt_more_entries the ring gets corrupted, but it's not the call
itself that corrupts the ring.

xengnt_more_entries start: prod: 3787 cons: 3787
xengnt_more_entries: map 0x1610ff -> 0xffffa0002da45000
xengnt_more_entries end: prod: 3787 cons: 3787
