Won't work. The requirement isn't from the aic7xxx driver, it's from the
scsi_obsolete.c code. It may help to switch the driver over to the new
error handling code, but so many problems were reported with that code, that
currently only three drivers use it, the 1542, u14-34f, and Dario's eata_dma
driver are the only ones that use the new error handling code. The new
error handling code uses a bottom half to complete the requests instead of
doing so synchronously during the interrupt context.
