Hi all,
this is a resend of the aic79xx update; I've removed the offending
copyright changes and merged patch 2&3.
Jeff, the inb/outb changes have been done by adaptec, so I really do
hope they've done proper testing on them.
I certainly haven't seen any untoward effects here locally.
Mark, were you able to test them? Or can you give some comments?
As already noted, I'll probably do another update to the latest adaptec
sources; wind and weather permitting as usual.
Please apply.
Cheers,
Hannes
