Hi,
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:
aic7xxx: <Adaptec AIC-7770 SCSI host adapter> at EISA 9 aic7xxx: BIOS enabled, IO Port 0x9c00, IRQ 11 (level sensitive), Revision >=E aic7xxx: Extended translation disabled. aic7xxx: Twin Channel, A SCSI ID 7, B SCSI ID 6, 4/4 SCB's, QFull 4, QMask 0x7 aic7xxx: Resetting channel A aic7xxx: Downloading sequencer code... 378 instructions downloaded scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 4.1.1/3.2.1 scsi : 1 host scsi0: Scanning channel A for devices.

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 :)
