I updated my system on Sunday. Since then there have been network problems: first the network is slow (even within a few minutes after booting) and eventually (12-18 hours later) the network - but not the rest of the system - just locks up (can't ping outside own machine). Rebooting fixes things ... temporarily. (Dmesg and config file are appended.) I've seen this before - I think I've _had_ this before - but can't find it in the mailing-list archives.
