Hi
Probably bug related to ESFQ, now i will unload module and will test more.
But probably not related, so if not difficult, please take a look.

Hi,
The main break seems to take place in HTB. Do you use HTB on IFB, BTW?
If not, maybe some exemplary rules from your script? (There are quite
a few modules loaded...)
Thanks,

I'd rather you were using my recent patches to SFQ instead of ESFQ. I
was able to crash a 2.6.24 user-mode Linux with ESFQ as well; I don't
know if that's what you encountered, but the SFQ patches should be
better anyway.

Hi Corey!
I've just had a look at your site, and see you're a bit disappointed about
the reception of your patches here. I don't use nor know about your work
(maybe some time...), and wish you better public here, but maybe you'll
find this story interesting: a few years ago, when I didn't even think of
reading netdev, I quite often visited pages of such projects as HTB (not
in every distro yet), IMQ or Julian Anastasov's. They were quite popular
subjects on admins lists, and I really admired people around these
projects, while the main kernel was something big and anonymous (no idea
e.g. about D. Miller). For the same reason I knew more about people from
iptables project - only because there was a need to visit this for some
non standard modules, and about A. Kuznetsov - only because of patching
iproute for HTB!!! (Only later I found that Alexey did more than needed
for several such HTBs.) So, it seems there could be good side of such
unofficial status too - if you only have something really useful for
others...
Cheers,

Thank you for the words of encouragement, but don't worry: I'm not going
to run away and hide just yet. :) I was a bit discouraged about not
getting reviews for the more recent patch submissions, though, and I
hope I don't come across as bitter about that. Patch review is a lot of
work, and I definitely appreciate the comments I received earlier--I was
able to make many improvements as a result.
In any case, kernel development progresses, and I now have to update my
patches so they can apply to current git. The ball has rolled back into
my court of its own accord; perhaps the playing field isn't level. ;)
