Hi Al and David,
After building the fresh 2.6.27-rc4-git5 kernel with your patch in commit 2f4520d35d89ca6c5cd129c38e3b11f0283b7d1b, I have this error on boot :
> Cannot open "/proc/sys/net/ipv4/route/flush" but networking works fine.
Do I modify something in my sysctl.conf file ? (see attached).
Thanks for your explanations,
Regards.
