I disabled IPv6 at the kernel source, make a new kernel without IPv6
at all, and I'm still getting those messages, so my guess is that
those are other machines as you suggest (my home network).

The browsers (any of them, firefox, chrome, epiphany, lynx, elinks)
still takes to much to resolv a name and download the content of it,
apt get stuck sometimes while updating, haven't tried anything else.

Anything else I can do to debug this problem ? so far it seems it is
this bug, but the release fixed doesn't work for me (and all the other
installation I've done over my work network).
