Hi, I'm having a problem with the ibm_emac driver for the built in gigabit ethernet on the 440gx. I was hoping someone could shed some light or at least point me in the right direction.
I'm using a GMS P502 board runing 2.4.27-pre3 (from GMS). The problem we are having is this: when we push data over the emac interface (eth0 and eth1 both show the problem), we sporadically get a "MAL: Rx descriptor error..." from mal_rxde in ibm_ocp_mal.c. Occasionally, the interface will "freeze up" for a few seconds. An ifconfig down/up will bring it back, but from then on it will freeze up again right away. It looks to me like this error indicates that we're out of RX buffers, but I don't how we would be running out. I'm no kernel or networking expert, but I thought the TCP stack would take care of throttling itself to prevent that sort of thing. I would appreciate any help.
