IWN hangs periodically on 10.0RC3

[Kevin Oberman]

My wireless has been periodically hanging since my upgrade from 9-Stable to
10.0-RC3.

iwn0 at pci0:3:0:0:        class=0x028000 card=0x13118086 chip=0x00858086
rev=0x34 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Centrino Advanced-N 6205 [Taylor Peak]'
    class      = network

It does this fairly often, but only when the network is busy. It never
seems to hang over-night. It usually seems to fail when loading graphics
heavy web pages. Restarting the wlan0 interface brings it back to normal.
(service netif restart wlan0).

I have been seeing this since I upgraded a couple of weeks ago and I never
saw it on 8 or 9.

Any ideas on anything I can poke or data i can collect? I used to have
issues that I resolved by turning off bgscan, but the symptoms were quite
different and seemed to have been fixed about a year and a half ago.
