You see the same exact thing with 3.0.6?

It works with 3.0.4 - do you need me to try 3.0.6 specifically?

but you said that if you use 3.0 domU with 2.6.18 you do not get the
type of warnings as above?

Correct.

Also, when the DomU guest starts it should report if it "thinks" it
supports barriers. Something like: blkbfront: xvda: barrier

Or is this the only message you get from blkfront??

2.6.18 dom0 + 3.0.4 domU produces this and nothing else:

blkfront: xvda: barrier: enabled
blkfront: xvdb: barrier: enabled

2.6.18 dom0 = works with 3.0.4, breaks with 3.1.

Thanks,
-Chris
