[sisela] ethernet 3com issue

Hi, i have an old p100 IBM laptop and am running an Orinoco wireless card and a 3com pcmcia card / adapter 3C562D/3C563D. when using the 3com ethernet card i get the following error - eth1: interrupts dropped if i use the 3com wired network and ping another decide, between every second ping i receive the eth1: interrupts dropped error message. does anyone have any suggestions on how to remedy this? Thanks in advance
