Weird.... I have it cc'd now, let's see.

Is there anything below this?
For the Falcon, I somehow suspect the DMA controller. Did you try running
NetBSD from the IDE drive? I don't know if this is an option for you. If
this helps, it makes sense to go diff-ing the SCSI-driver. I can also try
building a 1.2E kernel with an 1.1 SCSI-driver.

I'll do so ASAP. My Hades is currently building a snapshot - I'm having
trouble with ps too ;-) When this is up and running, I'll regenerate the
current.tar.gz file.

I hope so too...
