Subject: network stopped with a kernel error

hi guys, an problem occured, could anyone try to help me? i think it's
hardware error, but it's nice a second opnion
if i remove eth2 cable bond0 and everything work
the eth2 is running (yellow led on board) at 10mbps, but it's a
1000mbps (normally a green led on board) link, the other side is
running nice...
bond0 is a active backup bonding..
ethtool show eth2 and eth1 as up and running and eth2 as fibre but
it's a TP board?!
i'm considering eth2 a broken board now, but please check if i'm wrong:

It happens with old model r8169 boards that go south during netdev
whatchdog recovery handler.

Please send the XID line included in dmesg output at startup.

It may sitck stick until the device is not completely powered down / up.

It will help me if you have an URL for the sources of your kernel.
