Very interesting: I re-ran the fio test, but this time I configured
the smartd and hddtemp daemons to ignore the drives attached to the
Marvell controller. The test completed with no errors.
It certainly seems as if disk commands executed by the smartd or
hddtemp daemons are causing the exception.
Cheers,
