WARN_ON() in iwl_get_idle_rx_chain_count() gets triggered on system shutdown
when WiFi card is associated to an AP. This is on kernel built from
Linus' tree, commit 37cf95162af4036b4198756a590aab8126fa2ce4 (3.1.0-rc9+).
It looks HT-related, I can't reproduce this on 802.11g network.

WARN_ON() in iwl_get_idle_rx_chain_count() gets triggered on system shutdown
when WiFi card is associated to an AP. This is on kernel built from
Linus' tree, commit 37cf95162af4036b4198756a590aab8126fa2ce4 (3.1.0-rc9+).
It looks HT-related, I can't reproduce this on 802.11g network.
