Dear NetBSDers

I set up RaidFrame mirroring last week one of our 
Supermicro 6012P-6B. The have an Adaptec aic7899
chipset onboard with two identical Seagate ST336607LC
disks on it.

Returned today, to find the machine dead an displayin:

The system came up and everything could be fixed. 

The release is 1.6.1_RC1, dmesg follows further down.

What could be the cause for such a panic?

Thanks
Chris
