Hello everyone,

Here are the final results of my tests:
1. I reinstalled the router with vanilla 9.2-RC4 and performed the same
tests - the results were exactly the same. The problem persisted.
2. Then I applied the patch provided by Oleg and recompiled kernel. This
indeed did *fix* the problem and now creating/destroying vlans does NOT
cause the interface to flap at all. All the symptoms that I was
experiencing seem to be gone. Thank you so very much Oleg and Dmitry!

Jack, at this point I am wondering what your opinion on the patch is? Do
you approve it for production use yourself or do you think it needs to
reworked? Also any plans of incorporating this in -STABLE ?

Again, I'd like to thank everyone who helped here and especially Oleg,
Dmitry and Jack. Thanks guys!
