I have been trying to get a Intel Intellect server to work with the onboard
scsi controller and have failed so far. Since you seem to be the maintainer
for this part, i'll try you and cc: it to linux-kernel.
The machine is a Intel Intellect (latest bios), with a "Turbochip" from
Kingston. (This is a AMD 5x86 chip that fits in a 5V socket, works like a charm when using root on NFS)
The relevant scsi messages at boot (2.0.33) are:

I get similar results for 2.1.78 and pre-2.0 kernels, so either my system is
pretty broken, or this bug has been in there for quite some time. (Or both :)
