It didn't boot on my box, it hangs when scanning for devices on the 53C875.
I know that it makes it through ncr_queue_command in ncr53c8xx.c and
successfully queues the first command, but it doesn't get to queue another
one. When I get the time I'll try to see what happens after the first
command is queued.
