The WD1006SVR2 has a known history of locking up with ISC.  Something
to do with the card being unable to recover from errored seek aheads.
As I understand it the 1006 does multiple seeks and if one fails it
*should* go back and do single seeks, which it doesn't do correctly
thus it locks up.  BTW, ISC *said* they would have a work around in
the 2.2 kernel.  They don't.  I have seen the same thing with 2.2.
THe only fix I know of is to get another controller.  I went with
adaptec.  I have an associate that is going to switch a dtc7287 for a
wd1006.

Anyone have any experience with the DTC7287?
