Hi,

From time to time, I experience some complete network hangs:

Suddenly, all network connections become unresponsive. Even "ping
127.0.0.1" doesn't work. SysRq-w does not show any blocked processus.

When such hang happen, I have to reboot (shutdown does work).

This is not easily reproducible: it happens several minutes after 
boot (could be 45 minutes or 2 hours). I do not use heavy networking 
apps (like P2P). My typical usage is a Gnome desktop with  browser, 
mailer, IM, video or audio streaming. 

I have a single PC connected to a DSL router via ethernet (so no LAN 
with NFS or CIFS).

This happens with 2.6.23-rc8-mm2 and 2.6.23-rc6-mm1. I can't remember 
when I first see this problem. Maybe 2 months ago.

I attached the output of "strace ping 127.0.0.1". How can I collect 
some more data when this problem happens ?

~~
