Crash upon card speed negotiation


I'm using a 3Com 3c574_cs PCMCIA networking card in my Knoppix HD-installed laptop with a recompiled 2.4.22 kernel. This card formerly worked fine, but now I'm connecting to an Me box. to dump some archives. Right when my card is negotiating speed, I get this message:

"eth0: found link beat"

What used to follow was the (negotiated) 100Mbps speed. Now what I'm getting is a crash. I've included what I thought was relevant from /var/log/messages. The "cs: warning: no high memory space available!" messages I've gotten all along, even when the card worked, don't know if it's pertinent - the 'problem' seems to straighten itself out.

I found the answer ... I was browsing an unrelated thread, and discovered mii-tool, part of David Hinds' net-tools package. I used mii-tool to force 100-baseTx (i.e., no auto-negotiation), and life is good!

Now I need some guru help ... how do I:
* Write a script to force this ("mii-tool -A 110-baseTx -F 100-baseTxHD 100-baseTxFD eth0")

* Use the script upon startup to force 100-baseTx AFTER the card is initialized & BEFORE autonegotiation starts??

Any help welcomed!! :-)

Uh ... I guess I didn't find the problem. it's still freezing.

When I boot my original kernel, installed from the Knoppix CD, eth0 auto-negotiates its speed just fine, with no hangs. As it is the same (2.4.22) kernel, the problem must be in something I didn't compile in. I looked thru my config, but nothing jumps out as obviously wrong. Can I get a suggestion or two from you more enlightened types??
