This was just a patch I had lying around, if it worked it would confirm
my suspicion, which it has.

The minimal patch which is suitable for 2.6.23-stable and 2.6.24 would
be the attached one-liner. The "dpt_i2o: convert to SCSI hotplug model"
patch could be restored then.

(if the list eats the attachment, it's also available here:
http://www.miquels.cistron.nl/linux/linux-2.6.23+24-dpt_i2o-dma64.patch 
)

Anders, does this one-liner patch work for you ?

Mike.
