[Xen-devel] blkdev_name_to_number issues while running xenU

[Arun Sharma <arun.sharma@xxxxxxxxx>]

Anytime I try to start xenU, it fails the first time with the traces 
below. The second invocation is ok (but doesn't boot yet - still debugging).
blkdev_name_to_number() failures don't seem to be benign this time..
