I just thought I'd let you (and the aic7xxx) list know that I and at least
one other person (Craig Condit) also have this problem.  2.1.126 appears to
be the last Linux kernel that scans properly.  I've tried kernels up to 2.1.131-ac2
with the same results you have.

My configuration:

Adaptec 2940UW
UMAX Astra 610S
AMD-640 Chipset MB
AMD K6-300
128MB RAM

I sent a message to the Linux Kernel list about a week ago, but they were too
busy arguing about whether you'd get crushed by gravity if the earth stopped
spinning and I doubt anyone even noticed.
