2.4.0+aic7xxx doesn't boot, 2.2.17 OK

[Igor Mozetic]

Intel C440GX+ with on-board Adaptec AIC-7896 fails to boot 2.4.0:

SCSI bus is being reset for host 0 channel 0
SCSI host 0 channel 0 reset (pid 0) timed out - trying harder
... ad infinitum ...

In contrast, this is what I get from the 2.2.17 boot:

Any quick hint what to try?

I've got the same problem with the same hardware _but_ on 2.2.17
although 2.0.96 used to work fine.

Can I have your .config and your AIC firmware version in order to make a
little comparison.

Any other idea about the problem?

I saw the exact same problem on my Adaptec scsi controller.

I initially solved the problem setting the data transfer rate from 
80Mb/s to 40MB/s, but I see that yours is already 40MB/s, so this is not 
an option for you.

Later I saw an announcement from Justin T. Gibbs, who, I beleive, is 
currently developing an opensource driver for Adaptec.
You can find his patches for the Adaptec aic7xxx driver, for both 2.4.0 
and 2.2.8 at: http://people.FreeBSD.org/~gibbs/linux/

The patch makes all problems go away, and all my dics on the Adaptc 
controller is now running at full speed. (Great job Gibbs.)

I hope this helps you.

Yes, this solves the problem, thanks.
