You can try the boot parameter aix7xxx=no_reset. This let me get further
with an istallation than without this parameter. I have not been able to
finish formating (mke2fs) the disks on a Pentium Pro with an AHA2940
controller. Some have reported the the aic7xxx driver from the linux-2.0.12
kernel works for them. It has not helped me.
The problem appears to bo one of timing of multiple requests, as the
controller will read and write successfully the single sector required when
running fdisk.
I wish that I could be more help, but I do not know of a way out short of
buying a different controller. Please let me know if you solve the problem.
