Incompatibility/error in aic7xxx.o

[Axel Reichart]

Hello aic7xxx-development team,

Sorry to bother you, but i believe i found an incompatibility/error in
your aic7xxx-module for Linux.

My System consists of:
   - Fujitsu-Siemens LifeBook E-6570
   - Linux Kernel 2.4
   - SuSE Linux 7.1
   - Adaptec CardBus APA-1480B SlimSCSI

now for the problem:

When i start the PCMCIA-Subsystem, it works just fine. If i insert the
SCSI-Adapter in one of the Slots it is recognized just fine. But when
the aic7xxx-Module is loaded, i get some error-messages and the system
crashes (i attached the corresponding section of my /var/log/messages
file). Can you help me?

Thanks in advance,
