HangUp while Booting 2.2.16pre1-tobe

The hangup is caused when initalizing the first aic7xxx. There are two
aic7xxx (2940UW) in this Box (and another disabled one on the Mainboard).
If you need any more Information about the box and it's hardware, mail me.

There is no problem booting this box with 2.0.36. Booting with 2.2.16p1
locks the box while initalizing the aic7xxx. The box also locks up
when booting with 2.0.38 (we tested this some weeks ago ;-)).
While browsing the code I found many changes from 2.2.14/aic7xxx.c to
2.2.16p1/aic7xxx.c, but the server is high production, so I can't play
with it and boot it too often.

The 2.0.36-Boot-Message is:

(scsi0) <Adaptec AHA-294X Ultra SCSI host adapter> found at PCI 11/0
(scsi0) Wide Channel, SCSI ID=7, 16/255 SCBs
(scsi0) Downloading sequencer code... 419 instructions downloaded
(scsi1) <Adaptec AHA-294X Ultra SCSI host adapter> found at PCI 12/0
(scsi1) Wide Channel, SCSI ID=7, 16/255 SCBs
(scsi1) Warning - detected auto-termination
(scsi1) Please verify driver detected settings are correct.
(scsi1) If not, then please properly set the device termination
(scsi1) in the Adaptec SCSI BIOS by hitting CTRL-A when prompted
(scsi1) during machine bootup.
(scsi1) Cables present (Int-50 NO, Int-68 YES, Ext-68 NO)
(scsi1) Downloading sequencer code... 419 instructions downloaded

2.2.16p1 starts Downloading 396 instructions of the sequencer code and
then prints out something like
(0,-1,-1,-1) spurious interrupt during configuration, cleared.

If verbose is enabled it loops very fast some messages which i couldn't
read and remember. ;-)
The main problem is, that this box is high-production (nfs-)server for 30
(linux and solaris) clients. And we need to update because of many stale
NFS-Filehandles since we updated some of the linux-clients to 2.2.x.

Any Ideas for aic7xxx-Boot-Options like interrupts or mem-addresses?
I'm going to test plain 2.2.14 next days, but i'm not really happy with
that because of that Local-DoS-Exploit.

Maybe I would be happy with a workaround for the stale NFS-Filehandles ;-)
