Bult-in Network card on Asus P5B motherboard.
Downloaded and installed the r1000 v1.05 driver from the vendor, but the card is not working properly at neither speed 10 or 100 half or full duplex. I have not had the opportunity to test it at speed 1000.

The ping times on the local network varies from 0.1 ms to many seconds with a high average. Many packages are lost, so the card is useless in practice.

Tested on the amd64 build.

The v1.05 driver performs really badly and is basically useless. To get this network card working, you'll need to find the v1.04 driver. If you get a compile error while doing `make modules`, you will have to replace MODULE_PARM with MODULE_PARM_DESC, which appears 3 times on lines 51-53 of r1000_n.c

Built in NIC on Gigabyte GA-P35-DS4 doesn't work with CentOS 5.

Module (r1000) compiled for version 1.04 with minor edits to the source code (see above), but v1.05 fails to compile on my machine.

v1.04 works fine with the exception of jumbo frames support. Trying to change the MTU resulted in the following error:

SIOCSIFMTU: Invalid argument
