Log Message:
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.
