pci-err-7-symbios.patch

Adds PCI Error recoervy callbacks to the Symbios Sym53c8xx driver.
Tested, seems to work well under i/o stress to one disk. Not
stress tested under heavy i/o to multiple scsi devices.

Note the check of the pci error state flag inside an infinite
loop inside the interrupt handler. Without this check, the 
device can spin forever, locking up hard, long before the 
asynchronous error event (and callbacks) are ever called.
