3com 3C900 combo TX prob.

[Johan Lundgren]

Greetings,

I'm using a 3com 3C900 combo "Boomerang" network card in a high load (5
hits/sec) Linux web server.

I'm currently using kernel 2.0.35 and the network card driver version
0.99H. I recently upgraded to this card from an older ISA card (3C509) and
it has been going pretty well so far.

Once in a while though, from once a day down to once a week I get this
message in my logs:
 
 kernel: eth0: transmit timed out, tx_status 00 status e000.

 kernel: eth0: Resetting the Tx ring pointer. 

An ifconfig shows that the TX errors has increased by one. Is this a bug or
is there anything I can do to fix the problem? What causes it?

Thank you,
Johan Lundgren
