Well, if anyone can help debug the DNS problem with the ctx patch for the
-ac kernel;


Find out exactly what isn't working to stop DNS from working, give me an
exact description (eg, UDP packets to don't get through),
potentially isolating the problem to whether it affects localhost only,
external packets, etc ...

There was a small piece where the merge wasn't quite straightforward in the
2.4.21-pre4-ac6 patch that I did, that was in the UDP code. So if someone
can verify whether the problem exists in the 2.4.20-ac2-ctx16 patch and
nail it down to an exact functional cause (ie, using strace, netstat,
tcpdump) ... I'm sure everyone here with the crash problem would be

This kernel uses a completely different scheduler, so is guaranteed not to
have the same scheduling bug.

I've just been too busy of late to set up a test environment, vserver isn't
what i'm making money off any more...

What are you, a man or a mouse ? :-)
