hi, this old problem I had been faced with had been solved with 2.4.3-ac13/14, but now with kernel 2.4.4-ac9 and all other 2.4.4-acx it came up again. It's a Realtek 8139C chip on a AT2500 (allied telesyn or sumpin like that) Instead the former Apr 24 16:16:57 bello kernel: eth1: Setting half-duplex based on auto-negotiated partner ability 0000. I have now an unconnected cable which is not the fact:) May 16 15:20:26 bello kernel: eth1: media is unconnected, link down, or incompatible connection May 16 15:20:44 bello kernel: NETDEV WATCHDOG: eth1: transmit timed out May 16 15:20:44 bello kernel: eth1: Tx queue start entry 783 dirty entry 779.

(queue head) May 16 15:20:44 bello kernel: eth1: media is unconnected, link down, or incompatible connection Could I adjust some values, like tx buffer to get it to work? Please excuse my unscientific nature. I can as well supply any more information about the scenario...
