Your disk is corrupt.  This isn't anything like a valid label.
The first four numbers should all be small integers,
and the last one should be 0, 1, 2, or random >= 32.

I'd probably put prints in diskReadRaw and diskWriteRaw
giving the partition, offset, and data read/written, and
log all that to a file and then look carefully at it.
I suspect the Xen disk device driver.
