From the boot messages you have included below it seems that you have a Dell SAS-5i (Internal PCIe) controller and not a Perc/5[ie].
The SAS-5 known to have very poor performance (1Mb/s 100%busy) under certain loads (cvsup).
I have something that looks like the same kind of problem, on a PE860 with SAS-5i and two SATA 160GB HD in RAID 1.
The server is a webserver and "top -S" shows very high CPU usage (idle is 0%, user CPU is 40%, system CPU is 60%, interupt is 0%) when running 60 concurents httpd threads...
I've browsed quite a bit arround this issue and ended in this thread (plus several other threads arround the same problem).
I've just realised Dell has released a new firmware on 17 of april (beware of long URL) :
Has anyone tried it ?
