----------
After some investigation I've found that there were 2 commits to mac80211 between r16915-bb749e49a6 and r16957-3d026d2425:

7dd8829ef915f1c5fc728be8f8360c61ddaadf1b mac80211: improve rate control performance
f2c6d892cacb5d884bdd638bc7574c1ee98514a5 mac80211: add support for 802.3 encap offload with software rate control

After reverting these commits everything works fine - no crashes!

I'll try to figure out which of these 2 commits causes the crash. But it will take some time.
