Hi *,

I have problems with the new aic7xxx-Driver. These problems exist
with vanilla (2.4.4, 2.5.5, other d.k.) and -ac

When I built it into the Kernel, it will panic on boot when it tries
to access the adapter.

Built as modules it segfaults when i try to insmod (modprobe) it,
following this Oops in messages:

Does it crash with the USB-Driver?? But USB works fine... even after
the Oops

BTW: The old aic7xxx-Driver works fine for me

Devices connected to the adapter:
 - teac CDR
 - old plextor cdrom
 - ibm 4G HD

System is an AMD Thunderbird 800, 512MB, ASUS A7V

Do you need any further information?

Cheers
-Marc
