Lookinginto the SCSI protocol, it seems there is a 32bit number of blocks
(512Bytes) to count the LUN capacity. Thus roughly 4Gig times 0.4kB makes
2TB. I

Is this 2048 GB limit imposed on iSCSI? Because there is nothing in SCSI
itlself which forces you to this limit... Nowadays, you could have huge
partitions (if you do GPT partitions with PARTED)... So, if there is a
limit, it should come

Where did you get this kernel? Is it from xen or from Red Hat? If it is
from Red Hat? I have not seen some of the error messages in your log in
the upstream or RHEL code.
This is a xen kernel but distributed in the Scientific Linux official
releases. Check, for example:
