It works great under light network loads. However if put under a constant high network volume load it will "die" after some time and I get the message "ex0 timeout" and that's it. Only a "fastboot" will seem to get the laptop to reboot otherwise it hangs.
Set up a nfs share to another NetBSD box, in my case /usr/pkgsrc.
Then begin building really big things. I particular it dies while tring to extract big archive files that generate a lot of traffic, like lesstif, netscape communicator, etc.
I found that if I extracted the file before hand, on the other NetBSD box, the install doesn't generate as much network traffic and thus the ex0 interface seems to stay up okay.
I have a IBM Infomover that works under an laptop install kernel but not under a regular kernel, so I can't test to see if this happens with any other PCMCIA ethernet cards.
