What do these SATA errors mean / kernel 2.6.25.6 (DRDY ERR/ICRCABRT)

[Justin Piszcz]

Never had a single error so far, powered down my host, powered it back up,
and now with kernel 2.6.25.6:

Nothing was broken in any of the arrays and all seems to be functioning 
now but albeit at lower speeds as you see above UDMA/100 and UDMA/133. 
Could there be a bug with the new Veliciraptors and the drivers in the 
kernel?  I never saw this happen/occur with my old raptor 150s or 74s. 
Also, I stress tested all of these drives for 8hours+ and they never had a 
problem before so it makes the problem rather peculiar.

I am using the same cables/configuration, just new disks.  The smart tests
also show as good, is this a kernel problem?

Does/the kernel handle the ATA v8 protocol properly?
ATA Version is:   8
