My FBSD 960323-SNAP box went into a seizure this evening, after a reboot 
i was able to get the following messages out of /var/log/messages

I'm not even sure what these messages mean, and yes I know IDE drives are 
evil, but I didn't choose them.  Kernel config is normal except for:

disk            wd0     at wdc0 drive 0 flags 0x80ff
disk            wd1     at wdc1 drive 0 flags 0x80ff

Any clues hints or hey that's neat can you make it do it again's appreciated.
