Haldokló hálózati kártya, vagy kernel gond?

Hello

Tegnap elkezdett vacakolni az egyik gépünkben a hálózati kártya. Viszonylag nagy, folyamatos adatforgalomnál megáll. A logban a következőt találtam:

Ezután csak egy reboot segít (nem tudom a modult újratölteni, mert a gép több mint 70 km-re van). Reboot után megy egy darabig, aztán megint megáll.
RTL-8139 chipes kártya, 2.6.30.2 kernel, Debian 5.0.

Lehet, hogy haldoklik a kártya?
