Yes, or a problem with the qla2xxx driver. However, it's a bit
surprising that the hardware survived the stress test for more than
one day and went south just at the moment the fs was completely filled.

My first guess was that the problem might be caused by a reported
device size which is slightly larger than the actual size. But then

	ddrescue -i 7440Gi /dev/zero /dev/sda

would have resulted in a similar error. This command completed without
errors though.

Thanks
Andre
