Thanks for the report and nice description how to reproduce the problem.

The fix is not easy. In fact, it's as hard as to fix it by implementing
a feature that allows to use different rate control algorithm for each
device. Given the fact the problem doesn't occur in normal conditions,
it's a low priority for me (unless there is a volunteer to fix it). It
needs to be fixed before d80211 is merged, though (sigh).

I suppose you don't have automatic loading of modules enabled, right?

Thanks,
