PR/33445: Brian Buhrow: Fix a number of problems with the pdcsata driver:
The driver for the family of Promise SATA controllers,
/usr/src/sys/dev/pci/pdcsata.c is not very robust when it comes to handling
transient drive errors, or interrupt hickups when the card is under load.
Worse, my experience seems to indicate, and the Linux driver confirms,
that these cards tend to fall over rather frequently during high load
operations or if drives unexpectedly reset or go to sleep.  Symptoms
include interupt timeouts during heavy load, the inability to reset drives
if they go to sleep, and a failure of the card to generate interrupts at
all if the interrupt load gets too high.
