Ciao a tutti, sempre nella asrock H55/usb3 la scheda di rete non sente
il cavo collegato. Questo è l'output con lspci
# lspci -v -s 01:00.0

mentre ethtool eth1 risponde:

Qualcuno ha qualche consiglio? Dimenticavo: il kernel 2.6.30 su una
debian squeeze poiché il 2.6.32 non parte e si blocca subito dopo grub

Ciao
