I have a 2.6.27.20 system in production, the e1000 drivers seem pretty "noisy" allthough everything appears to work excellent.

dmesg here: http://krogh.cc/~jesper/dmesg-ko-2.6.27.20.txt

The system has been up for 14 days but the dmesg-buffer has allready overflown with these.

Configuratoin is a 4 x 1GbitE bond all with Intel NICs
