Ah sorry, that's a legacy of when I had considerably less ram than 2GB. I only use firewire on the rare occasion that I want to grab some video from my camera and I use the parallel port even less frequently. So one of the last things that happens in my rc.local init script is that I unload the related drivers. > > Also, in http://lkml.org/lkml/2008/6/1/2 you reported a patch which > changes the SCSI core's interaction with the driver core as first bad > commit.

When I was bisecting, I assessed good or bad based on whether I experienced the long pause during boot up. You may have seen my reply to James a short while ago that I have bisected again and arrived at the same patch.
