kernel panic with 2.5.67-ac1

[Christian Staudenmayer]

hello,

i recently compiled 2.5.67-ac1 on my machine which uses the
aic7xxx driver for an old adaptec 2940 scsi controller.
When booting, the kernel panics after loading the scsi driver
with the following message:

Process swapper (pid: 1, threadinfo=dbf8e000 task=dbf8c040)

 <0>Kernel panic: Attempted to kill init!

Note: this does not happen with 2.4.20, 2.4.21-pre7, 2.4.21-pre7-ac1 or 2.5.67-bk8
It does, however happen with 2.5.67-ac2, but the error message is some lines longer
and some of the addresses have changed.

I'd be really grateful for any insight on this problem.

Greetings, Chris
