[tulip] Errors when busy network traffic with linksys lnx100 card

[Rob Mantel]

I posted this question a couple of weeks ago already, but then didn't get
any reply. Since I still have the problem, and have not been able to get any
closer to a solution, I will try posting again. Sorry for the redundance but
I would really like more information about what's going on here.

Occasionally (usually when network traffic was very busy) with the tulip
driver I was using I used to get time out errors that made me have to
restart the network to get my linux box connected to the network again. So
in an attempt to solve that problem I updated my network drivers to v0.92t,
and now instead of the time out errors when the network gets very busy, I
get 'too much work during an interrupt' errors.

the following is an example from /var/log/messages before and after the
upgrade to v0.92t.

Any ideas what can cause this or what I can do to solve this? Any help or
information would be greatly appreciated.

Thanks,
