No biggie. I'm not in a big hurry. Dual-boot is nice -- I'm still running
RH8 most of the time.

Well, that's helpful, in terms of pointing to either the newer kernel, or
FC-only patches. It also suggest that maybe bringing this up to the Fedora
community would be the thing to do.

Oh, I wish I could play with a protocol analyzer. Those are rare fish
these days. I don't even know where I might borrow one. The occasions on
which I think I need a breakout box are pretty rare. In fact, the last
time I wanted one was over a year ago, and I wound up solving the problem
by other means.

I'm still of the opinion that if I can just discover the proper debugging
switches to put into place, that this is solvable using software
debugging, without resorting to trying multiple kernels to see what works
and what doesn't. Add in the myriad possible combinations of patches, and
this quickly becomes a unworkable. (IMHO)
