SubjectLoss of network connectivity

Hello,

Hope this is an OK place to send this.

I am running on a Compaq Armada E500 laptop, and after about a days worth
of the pcmcia network card being registered, the system looses network
connectivity with the following being logged to /var/log/messages


eth0: transmit timed out, tx_status 00 status e000.

I am running pretty much stock Redhat 6.1 with kernel 2.2.17 and
pcmcia-cs 3.1.20

The card in question is a 3Com 3CCFE575BT

Ejecting and putting the card back in fixes the problem for roughly another
24
hours.

Upon re-inserting the card this is logged

Looks OK to me?

Any help would be much apreciated.

Also

If you can CC any replies to me, as I'm not on the list.
