I must add that after I upgraded I added an hdd monitoring script for munin
to my config to watch HDD temps. This happened when munin ran it.
The disks it's being ran on is sd[c-h] which are on the onboard aic94xx chip.
All 6 disks are segate 750gb sata.
Also, this only happened once so far (On the first run of 2).
