AHA-2940 and linux kernel 2.0.32

I recently installed kernel 2.0.32 (Redhat 5.0) and I
noticed different messages when booting up:

Warning: detected auto-termination please verify
driver detected settings and use manual termination
if necessary

Does anyone know what the cause/solution to this
problem may be??

I think this may also be giving me problems with my
CD-Writer which dies when trying to write a CD.  
The writer is the last device on the SCSI chain,
i.e. it has physical termination.  When I use
an older kernel (2.0.18) which doesn't produce the
same warning messages, the CD-Write seems to
work fine.

Looks like Linux 2.0.32 does not want a controller to auto-terminate itself. The adaptec AHA2940 has got a feature called auto-termination. this means that the controller is able to detect 'on the fly' if it is at the end of a local scsi cable and then terminating itself with an active termination circuit enabled by the controller-bios. you can switch that off by entering the bios-setup utility of your 2940 via entering ctrl-A or something like that at system startup and before detecting scsi-devices. look at the menus and turn off auto-termination. this should fix your problem.
Note: you do not need to terminate your adaptec 2940 by hand if it resides at one end of your scsi-cable AND auto-termination is ENABLED. but if you turn off the auto-termination you MUST enable the termination manually in the controller-bios. Optionally an external active (!) terminator should do.
