Hi everybody. I'm using a Tyan Thunder K8WE (S2895) mainboard with two 2,2 GHz DualCore Opterons (AMD Model 275). The mainboard has two GigaBit Ethernet Network Cards (one from Nvidia nForce Professional 2200 chipset - attached to CPU 1, and one from Nvidia nForce Professional 2050 - attached to CPU 2). Ok I've configured the network options in the kernel the same way it always worked for me. The network driver in der kernel is set to forcedeth (which should be the correct on for this ciphset). I'm connected to internet via PPPoe (PPPoe module of the kernel),... using pppd(8). Sometimes I get strange disconnect errors. At first the ping time continue to rise to extreme values (frome about 14 ms to 80000 ms). And I get the following errors (from syslog) Oct 2 20:53:24 fermat kernel: NETDEV WATCHDOG: eth1: transmit timed out Oct 2 20:53:54 fermat last message repeated 3 times Oct 2 20:54:53 fermat last message repeated 6 times Oct 2 20:55:53 fermat last message repeated 6 times Oct 2 20:56:53 fermat last message repeated 6 times Oct 2 20:57:23 fermat last message repeated 3 times Oct 2 20:57:24 fermat ntpd[2805]: kernel time sync enabled 0001 Oct 2 20:57:33 fermat kernel: NETDEV WATCHDOG: eth1: transmit timed out Oct 2 20:58:13 fermat last message repeated 4 times Oct 2 20:58:53 fermat last message repeated 4 times Oct 2 20:58:56 fermat pppd[2137]: Terminating on signal 15 Oct 2 20:58:56 fermat pppd[2137]: Connect time 11.6 minutes.

But I can not reconnect immediately,... but after some time pon again works. The problem always occurs when mldonkey-server (from the Debian packages) is running. When I deactivate this deamon no errors occurs. Of course mld access the network but I don't think that the error is in that package. And of course it don't run with root privileges. So it should be able to crash the network. Any help would be apreciated. Regards, Christoph. |
