Can you send your complete dmesg (especially the XID line) and a complete
lspci -vvxx  of your system to identify the network device ?

The content of the /proc/interrupts file would be welcome too.

You may try http://userweb.kernel.org/~romieu/r8169/2.6.26-rc9/20080710/
but it's more or less a shot in the dark for now.
