RED HAT 6.0 and SCSI ???

[Noah Fields]

Brad,

There is a thread over at comp.os.linux.setup about the 2940UW card and RH
6 (note that everyone sais 5.2 works fine, but 6 causes trouble...) So at
least it seams that you are not alone.

I could not find articles at RH knowlege base though. (they had some
general info on trouble shooting the 2940's but nothing specific to RH
6.0... )
