SCSI issues

Problem:
A faulty cable connection was causing intermittent problems with the scsi bus. The 2.0.x kernels, the command would time out, bus would reset, log an error and the machine would come back to life and
work for an undetermined amount of time and then repeat.

With the 2.1.x kernels that I have tried (>2.1.80) so far, the system locks up solid. I've tried the standard aic7xxx drivers and the updated drivers. In any event, the lock up doesn't log any
information to a file or the console.

I unfortunately don't have any other brand of scsi cards lying around to see if this is hardware specific.

I'm not sure if the 2.1.x behaviour is what to be expected. Cable is fixed so I don't think I can reproduce the problem, but I would be willing to try.

Machine Setup:
2.1.8x and 2.1.90 kernels - configured with SMP=1 commented out.
ppro 200
adaptec 2940uw
quantum viking drives

cheers!
