2.6.6 Kernel + Adaptec aic7890/91 = Kernel panic

2.6.6 Kernel + Adaptec aic7890/91 = Kernel panic

[Ralph Bergmann]

Hello!

If I use the 2.6.6 kernel, I get a "Kernel panic" when starting.

I use a Debian unstable, last update 31.Mai 2004.

Kernel:
kernel-image-2.6.6-1-686-smp

System:
0000:00:00.0 Host bridge: ServerWorks CNB20LE Host Bridge (rev 05)
0000:00:00.1 Host bridge: ServerWorks CNB20LE Host Bridge (rev 05)
0000:00:01.0 PCI bridge: Hint Corp HB6 Universal PCI-PCI bridge 
(non-transparent mode) (rev 13)
0000:00:04.0 Multimedia audio controller: Ensoniq ES1370 [AudioPCI] (rev 01)
0000:00:06.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 
100] (rev 08)
0000:00:0f.0 ISA bridge: ServerWorks OSB4 South Bridge (rev 4f)
0000:00:0f.1 IDE interface: ServerWorks OSB4 IDE Controller
0000:00:0f.2 USB Controller: ServerWorks OSB4/CSB5 OHCI USB Controller 
(rev 04)
0000:01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 
AGP (rev 85)
0000:02:01.0 SCSI storage controller: Adaptec AHA-2940U2/U2W

Error-Message:
SCSI subsystem initialized
FATAL: Error inserting aic7xxx 
(/lib/modules/2.6.6-1-686-smp/kernel/drivers/scsi/aic7xxx/aic7xxx.ko) Nu 
such device
pivot_root: No such file or directory
/sbin/init: 424: cannot open dev/console: No such file
Kernel panic: Attempted to kill init!

The kernel-image-2.4.25-1-686-smp works fine.

Does someone have an idea?

First of all I have to excuse, because you have to wait so long for my 
answer. But I've got good news: the problem is partially fixed. I put 
the scsi-adapter in another pci-slot (now a 32bit one in contradiction 
to the 64bit one I used before), and now it's working. But I've got some 
questions concerning this:

1. should it have worked, no matter, which kind of pci-slot I use? When 
i used the 2.4 kernel, there were no error-messages, but when i switched 
to 2.6 kernel, I run into trouble as you know... So is it a 
kernel-problem or a hardware-thing?

2. And if you want to have the specific output nevertheless,  I would 
prefer, that you send me the special adjusted file I have to use, 
because I have no idea about kernel-programming at all...
