just a note,
make sure you do a clean install of 4.x-STABLE (<<very important...prior
versions do not work...though compatiblilty is claimed...) when using
the PERC2.  Otherwise you will get "wedged I/O controller" errors...in
my case, during cvsup, during build world, during build kernel...during
install of 4.0(pre-stable)....
i hosed a poweredge 4400 because of that card (and the resulting fsks
due to the above error) and had to use 4.1-RC snapshot to get it
working...not good in a production environment...on the bright side
though...no major problems since.
