Yesterday I started using CBQ in production on our firewall over an IMQ
device, but since then I get a lot of messages in my syslog like below:

Any idea what may cause this? It really seems CBQ is causing this. I am
running IMQ for a few days now, but without doing actual shaping, and I the
syslog remains calm. But from the moment I added CBQ I get lots of these.
Doesn't look like coincidence to me :)
Thanks in advance for any help.

Oops, forgot to mention the machine config.
It's a kernel 2.4.16 box using a stock kernel with only the IMQ patch and the
mangle5hooks patch, and the Cyclades HDLC driver. The IMQ device itself is
the aggregate of our three 2Mbit HDLC links (hdlc0-2).

Figure out what the initial message is - this just lists the fact that
messages have been suppressed.

Doh... I should have thought of that myself :-/
Anyway, these messages are *followed* by things like
Nov 14 17:02:10 firewall kernel: NET: 1 messages suppressed.
Nov 14 17:02:10 firewall kernel: protocol 0008 is buggy, dev hdlc1
Nov 14 17:02:10 firewall kernel: protocol 0008 is buggy, dev hdlc2
But there are no messages (besides rather big iptables logs, but what do you
expect on a frontend firewall with a class-C behind it ;-) preceding the
'messages suppressed' warnings.
I have no idea what '1 messages suppressed' means, much less where it comes
from. All I know is that I get it since we started using CBQ.
