I removed this test and then the next run (after reboot) hangs at xfs/073 with
a lot of errors in dmesg like

	XFS (loop2): Failing async write on buffer block 0x9600790. Retrying async write.
	blk_update_request: I/O error, dev loop2, sector 8389920
	loop: Write error at byte offset 4295647232, length 4096.

Oleg.
