Hi Arjen,
I suspect you are being hit by the scsi layer here - you are seeing two
error reports, the first one is the scsi layer reporting an error, the
second is xfs reporting it got an I/O error from the scsi layer.
Apart from hex vs decimal, they are both complaining about the same
disk block.
Have you tried some raw I/O tests to the same device without a filesystem
on it?
