Hi, gibbs :
It's me again ... :(
I just tried the latest kernel and the ahc_intr message appears again.
aic7xxx.seq v1.39
aic7870.c v1.36
aic7xxx.c v1.71
I remembered last time when I saw this message, and it was cured by
applied the pentium-bcopy-patch, so I applied the pentium-bcopy-patch
again, and it works again. (can't figure out why)
Here is the verbose boot message, and a diff against the message
from the bcopy-patched (working) kernel.
My 2940 is an AHA2940-S76/AUTO (non-Ultra) with v1.23 BIOS
