I have the same problem. I couldn't install RedHat5.2 (2.0.36) (mount
failed,  after scanning the scsi-bus).
RedHat5.1 (2.0.34) aic7xxx-5.1.10 was successful. 

Trying the 2.2.[0-2] showed the same problem. Adding some boot-options,
like: aic7xxx=no_reset  aic7xxx=extended  aic7xxx=no_probe   didn't help.
(How to append two an more options in lilo.conf ?)

I've tried booting without any CDROMS and on both Channels, tested
some options of the SCSI-Adapter, limited the speed, checked the
termination several times, ....


The config is some different:
Tyan Thunder S1836DLU-BX (BIOS 1.16) with AIC7895 (UW)
IBM DRVS UW

I could post all config and error logs but it's about 20k.
I'm wondering why it works with an older kernel version 2.0.34
(compiled with SMP-support).

Some new features in the SCSI driver, that results my kernel-panics?
