Adaptec driver broken

[ktindle]

I have a SCSI controller in a 32-bit PCI slot. Worked in SL 8, broken in SL 9 with the 3.4 kernel.
The aic7xxx driver is suddenly unhappy, to wit:

'lspci -k' output (extract):

01:07.0 SCSI storage controller: Adaptec AIC-7850 (rev 03)
Subsystem: Adaptec AHA-2904/Integrated AIC-7850
Kernel driver in use: aic7xxx

'dmesg | grep aic' output:
