I can reproduce this Oops in 2.4.26 using Jason's tc commands:

...and running my tc-graph.pl script 
(http://www.metamorpher.de/files/tc-graph.pl) afterwards (you probably 
have to change two variables at the top of the script, namely DEV for the 
device and BIN_TC for the location of your tc binary).

It kind of killed my router, my NIC didn't get detected after reboot 
anymore, but that may have been just a really, really bad coincidence.

Someone on this list who is particularly interested in this stuff?
