Nvidia network card dumps thousand error messages in dmesg


apparently many people have the problem with this nic and linux but there are no solutions that i could find for centos 5.2. Here is output for all the relevant commands. For dmesg the output is much larger than what I copy/pasted here but I just included all the relevant parts once.

thanks for all the help

uname -r
2.6.18-92.el5

OS
centos 5.2

lspci | grep -i ethernet

00:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3)
00:09.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3)
80:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3)

It's the same as dmesg

kernel: eth0: Got tx_timeout. irq: 00000037
eth0: Ring at 22695e000
eth0: Dumping tx registers
0: 00002037 000000ff 00000003 029a03ca 00000000 00000000 00000000 00000000
20: 00000000 00000000 00000000 00000000 00000001 00000000 00000000 00000000
eth0: Dumping tx ring

It repeats manhy times. I only included error messages once.

Quote:
The root of the 5.2 issues is some MSI problems in 2.6.18 that were fixed in
2.6.19 and later. Those patches will soon be added to my test kernels and will
appear in the kernel version:

2.6.18-94.el5.gtest.50
Is there a kernel update available for your Centos Box that you can apply ? Your current kernel version appears to be earlier than the patches to the forcedeth driver were applied.
