Package: network-manager
Version: 0.9.4.0-3
Followup-For: Bug #649205

Dear Maintainer,

I am experiencing exactly the same problem.
Symptoms are:
- /etc/resolv.conf is constantly recreated;
- NetworkManager has a very high CPU usage (>50%). strace shows that it keeps
  chatting over a netlink socket;
- it floods syslog, even more in debug: it clearly loops.

NM seems unable to handle properly the RA from my router.
So it keeps refreshing resolv.conf and i guess the whole network configuration and spams every second:

May  8 16:10:36 powerbook NetworkManager[8280]: <info> Policy set 'Auto freebox_ABCDE' (wlan0) as default for IPv4 routing and DNS.
May  8 16:10:36 powerbook NetworkManager[8280]: <info> Policy set 'Auto freebox_ABCDE' (wlan0) as default for IPv6 routing and DNS.

Disabling ipv6 on my home router (Freebox Revolution) made the problem disappear.
