Since I moved to x86_64, I also see this bug. Mostly directly after the machine ist powered up, one ifconfig down / ifconfig up normally fixes it.
Additional infos: - seems to happen only with the wlan interface (iwl3945) - used guessnet on the same machine with 32 bit for 2.5 years with no single occurence of this. Question: Would a strace of a guessnet run be of any help? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
