I see this as well on my PE800.

I get this as well.  I don't use USB so I turned that off at the BIOS  
and removed it from my kernel, but I still get "interrupt storm" on  
my bge0 device.  No idea why.

Performance is not all that great on this box disk-wise, but CPU wise  
it is acceptably fast.  I run FreeBSD/amd64 on it rather than FreeBSD/
