Hello,

I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ).

I configured one HTB qdisc on an IMQ device. This qdisc has some classes
(about 5) and all of the classes has qdisc pfifo.

I sometimes got out from my linux (while I was working) and I found in
logs:

Dec  4 11:49:27 core kernel: HTB init, kernel part version 3.7
Dec  4 11:49:28 core kernel: HTB: quantum of class 10020 is small.
Consider r2q change.<7>htb*g j„81720

and once:
Dec  4 13:47:10 core kernel: eth0: Transmit error, Tx status register 82.
Dec  4 13:47:10 core kernel: Probably a duplex mismatch.  See
Documentation/networking/vortex.txt
Dec  4 13:47:10 core kernel:   Flags; bus-master 1, dirty 57343(15)
current 57343(15)
Dec  4 13:47:10 core kernel:   Transmit list 00000000 vs. dec105c0.

My interfaces:
eth0 : a VLAN trunk interface
eth1 : not used yet
eth2 : my interface the IMQ is attached on (PRE- and POSTROUTING chains).

(rev 78)
00:0e.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado]
(rev 78)

I tryed to make some download tests and it didn't work and I got out from
computer (I don't have a monitor connected to the comp. - only a serial
console port:).

What can I do with that? How can I fix the problem?

	Thanks

...probably similar thing has happened before (I didn't have the serial
console, so I don't know).

I didn't find anything useful in messages logfile...

Regards,
	Thomas

p.s.: I use gcc-3.2 on Athlon-XP 1700+ with 512M RAM (and again:
linux-2.4.20-ac1 on RedHat 8.0)

Same problem here, until I found that one should (must?) use different
IMQ devices for PREROUTING and POSTROUTING.

Many, many thanks Razvan!!!
It was the problem. I removed one PRE- or POSTROUTING rule and see the
magic: I can't reproduce the kernel panic.

So now the question is:
Is it possible to use the SAME IMQ device for ingress and egress trafffic
(as I tryed to use)? If not, why, and if yes how?

Thank you again,
	Thomas
