[epic] epic100, kernel 2.4.18 -- timeout,

[Alexis Zubrow]

hi.

I'm a relative newbie to linux.  I was using the epic100 for a
smc9432btx card under the 2.4.17 kernel.  Everything was fine.  I upgraded
to the 2.4.18 and I seem to be having problems with getting my card to
work. I've consulted what documentation I could find, the mailing
lists, and a diagnostic program (epic-diag).  Despite this, I haven't
had a ton of luck figuring out why the card seems to  be continuously
timing out every time it tries to make a connection.

I've tried a bunch of diagnostics and triple checked my configuration, but
I'm not sure where to go from here.  Any suggestions on how to tweek
either the start up configuration or the driver?

Thanks in advance,
Alexis
