Well if i were you, i'd try to narrow down the problem.  You have DMA  
errors.  Try disabling ultra dma on your ata controller for your  
drives individually until the errors stop or all are disabled.  If  
the errors stop with all the drives off, there must have been a  
negative change to the promise driver or previously your controller  
was not using ultra dma and it is now.

It sounds like you have some nice hardware, but i've found that  
FreeBSD 5.x and 6 beta is picky with AMD ia32 based machines.
