I have been seeing this in much the same circumstances, I was attempting
to use a raid1 array of nbd devices, but it wouldn''t make it through
the
sync most of the time. I was never able to prove one way or another if
it was the bridge code or xen causing a problem.
I''ve gone back to iscsi, but haven''t really tested it much as
I''m
hacking the iscsitarget enough to get it to run on 2.6 (it compiles now
but oops''s. doh!)
