I used to get that error prior to 5.3-BETA3 (5.2.1-RELEASE, and all
previous 5.3-BETA's). Randomly after reboot the machine would spew
about 100 of these and then hardlock. I've got two identical boxes
running BETA3 and BETA7 without any issues.  Intel 6300ESB controller
and Western Digital "Enterprise" Serial ATA Raptor drives are the
hardware.

I thought about posting the issue, but decided against it since it was
BETA 1 or BETA 2 and 5.2.1 was, honestly, nothing but pure crap.
