No problems.

However, there is a real problem with eepro100 when the system resumes
operations after a sleep.
May be, you could guess what's wrong in this case?

Best regards
Andrey

Well, it appears *something* like that is happening. However, I can't think
of how to fix it. Everything goes "disabled".

Attached are the two 'lspci -v' executed pre and post-suspend. Also attached
is a diff file between them. If you have any further ideas, please e-mail me
back?

Scott.
