Bug Description

Binary package hint: linux-source-2.6.22

A simple setup:
--
tc qdisc add dev ppp0 root handle 1: prio bands 5 priomap 4 3 3 3 3 3 3 3 2 2 2 2 2 2 2 1
tc qdisc add dev ppp0 parent 1:1 handle 10: sfq
tc qdisc add dev ppp0 parent 1:2 handle 20: sfq
tc qdisc add dev ppp0 parent 1:3 handle 30: sfq
tc qdisc add dev ppp0 parent 1:4 handle 40: sfq
tc qdisc add dev ppp0 parent 1:5 handle 50: sfq
sudo tc filter add dev ppp0 protocol ip parent 1: prio 1 u32 match ip dport 22 0xff flowid 1:1
sudo tc filter add dev ppp0 protocol ip parent 1: prio 1 u32 match ip sport 22 0xff flowid 1:1
--
Now, ssh traffic would get to the 1st flow which is supposed to get dequeued first. Though, under a heavy load (packets with no TOS set, going through 1:5) ssh sessions would still suffer greatly, like there's no QOS applied at all.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
