>Description:
Suddently my machine "lost" the connection with the network, and only a hard reboot fixed the problem. I got the following messages in the kernel logs:

<<6>6>nneewwnnffss  sseerrvveerr  119922..116688..00..225544:://hhoommee//mmaaggee::  nnoto t rreespsopnonddiinngg

ale0: link state changed to DOWN
ale0: could not disable Tx/Rx MAC(0x00000004)!

This is with:
