Re: Kernel 2.2.1-pl6 problems on Ruffian

With regards to your message at 06:24 PM 02-18-99 +0100, Brederlow. Where

I think you will find that your problems are indeed cable/termination/cable
length related.
We build and use the UX ( the new name) based systems and have none of
these issues, as long as we use cabling under a total of 1m, active
terminators ( no not the ones built-in on the drives). The 53-C8xx drivers
work well. Maybe check the version. Current ones are:
- ncr53c8xx-3.1e      (8XX generic driver)
- sym53c8xx-1.2       (896 driver)


Good luck!
