Unfortunately, your Oops doesn't contain symbol infomartion for modules.
Did you really follow the steps in Documentation/oops-tracing.txt?
> Module Size Used by Tainted: PF
> ppp_mppe 23320 0 (autoclean)
However, i still have a sneeky suspicion, that the bug is in ppp_mppe (why
did you have to load it using insmod -f?). IIRC from discussions before, a
compressor is not allowed to grow a packet, but when using encryption this
might well happen. If then ppp_mppe calls skb_put to update the len field,
it will trigger the above bug() and cause the oops.
So better check why the above trace misses the module information and if
the trace really shows ppp_mppe in the path, forward the problem to the
PopTop people ;-)
