[smartmontools-support] Problem while running long device test

[David C. Partridge]

I have an Adapted 51245 Raid card, I installed a new device and defined a
simple volume on that device, and then started a long smart test:

 smartctl -t long -C -d aacraid,0,0,7 /dev/sdc

this started fine, but some few hours later I got this in syslog:

The system was then hung.  I'm wondering if the problem occurred because the
test was still running in foreground mode and that the attempt to read smart
data was blocked as a result.
