Not very surprising, which is the actual interrupt used for SCSI
(it should be in the doc and in the residual data).

Tell me if the zImage-2.2.0-pre5 on ftp://vcorr1.iram.es/pub/ works
better. Early boot messages will be different and it will try to use
the OpenPIC (that's the image running on my MVME2600 right now).
I'm completely reorganizing my source code and patches, hopefully
I'll be able to make it available during the week-end. 

	Gabriel.
