Hm. I had to deactivate that piece of code, because it was causing
problems with PPR negotiation (with U320 drives) in the ahd driver,
which is very similar in structure.

When I tested the ahc driver, it still worked fine on my machines.
Maybe the change wasn't completely correct, and some recent
SCSI probe reshuffling exposed the problem.

Can you boot the kernel with the -v flag and mail me the output?
