[Click] click + xen + PollDevice problem

[Manel.Bourguiba at lip6.fr]

Hi all,

I am using click with xen, a Core 2 duo processor and a quad port e1000
card. With a simple configuration like this:
PollDevice(peth4) -> Queue(1000) -> ToDevice (vif1.1), there is no
problem, but when I add a classifier like :

PollDevice(peth4) -> C1::IPClassifier (10.0.0.6, 10.0.0.7)
C1[0] -> Queue(1000)-> ToDevice(vif1.1)
C1[1] -> Queue(1000)-> ToDevice(vif2.1)

The system crashes, it uses 100% CPU and I have the following dmesg output :

Unable to handle kernel NULL pointer dereference at 0000000000000c RIP
Modules linked in : click proclikefs button battery ac ip_contracks e1000
fan thermal processor
Pid: 17112, comm: kclick Not tainted 2.6.18.8-xen0

I did the same thing with FromDevice, it worked even with a more complex
configuration. So the PollDevice is the cause.
I enabled multithreading when configuring click, but i had the same problem

I would appreciate your help.
Thanks
