This is new one to me! I guess my 3 x UATA-100 are super drives of some sort not to crash!!

I have had this case on one machine running FreeBSD 5.4, it would happen intermittently, but after replacing the power supply it appears to have resolved the issue. Also, once I noticed this problem with MegaRac G2 remote management card installed!

However, when you've upgraded to FreeBSD 6.0, did you test the system extensively for long period of time before upgrading to 6.1-RC ? If it worked well in 6.0 and stopped working in 6.1, I've to lean towards SW issue assuming all things remained the same.
