This is my first foray into 2.4.X kernels. I did not have any panics with
the old aic7xxx driver. I first used 6.2.1 in kernel 2.4.11. So you
pretty much know the whole story. The reason I moved to your 6.2.4 was
that at some point I could not even boot 2.4.12 since it came back with:
scsi0:A:1: ahc_intr - referenced scb not valid during seqint 0x71 scb(0)
Kernel panic: for safety
In interrupt handler - not syncing
<0>Rebooting in 180 seconds
But the message logs never caught any of the error message since a sync
was not done.

I have to go out of town tonight but I will rebuild with this define and
send you a full error message log on Wedsnesday.
Thanks, I hope we can get this nailed down. I really would rather use
your new driver.
