Send but not receive using Thinkpad with 3Com PC Card
My network card is recognised and appears to be sending but not receiving data on the network.
I have a Thinkpad 600E with 3Com Megahertz 3CCFE574BT PC Card. It worked fine with Debian Sarge using a 2.4 kernel, but I'm having trouble getting it to work with a 2.6 kernel.
I've tried Debian Etch (4.0r0) and Knoppix (5.0.1). In both cases, the card *is* recognised. It fails to get an IP address using DHCP. I can manually assign an IP address, but it then fails to ping the router or another host on the LAN.
I have used Wireshark to try to figure out what is going on. I can see the laptop sending a DHCP request, but not receiving a response. With a static IP, I can see the laptop sending ARP requests, but not receiving responses, even though I see the ARP responses are being sent.
Pretty weird, no?
In dmesg I notice a couple of "eth0 interrupt(s) dropped!" messages.
I'm not sure where to go from here, so I'd appreciate any suggestions.
