[eepro100] EEpro100, Red Hat 7.1, wait_for_cmd_done timeout errors

[David B. Ritch]

Bigger release numbers are apparently not necessarily better. ;-)

Unfortunately, we need to stay with 7.x in this case.  What kernels did
you use?  The stock RedHat kernels?  Some from www.kernel.org?

Apparently, with 7.1 and new drivers the problem was there, but with 6.2
and old drivers, it wasn't.  So - I wonder about 6.2 with the new
drivers, and about what differences other than kernel and drivers that
might affect this.  At one point, we had some ribbon cable PCI extenders
that cause all sorts of problems, and appeared to contribute to this. 
When we went to riser cards, the system was *much* more stable in many
ways, and this problem soon disappeared - until we moved the system.

Well, we're turning this cluster over to our client, so I won't have a
system that we know is exhibiting the problem to experiment with. 
However, the problem will bug me, and I suspect our client will, too, if
this arises again, so I'd like to have a better handle on it.

I guess I'll keep watching and listening.  Maybe someone will solve it. 
Or maybe it just won't come up again on my equipement...

Thanks!
