The fix is here:
http://marc.info/?t=124942266800001&r=1&w=2
kmemcheck wasn't helpful at resolving it, as the problem was with
writing after the end of allocated memory, not with reading
uninitialized memory. SLUB debugging nailed it as soon as I took care
to understand what it was telling me.
As for the issue you found by kmemcheck, it's most certainly unrelated.
If you can reproduce it with the rt2xxx patch, consider reporting it to
the netdev list. It would be helpful if you find what line is
triggering it and include your .config file.
