Ok, starting to look into this ...

Since it seems you get this all the time, could you please put a printk
into net/wireless/scan.c in cfg80211_inform_bss_frame where it sets
res->pub.beacon_interval, and print out
	"%p %d", &res->pub, res->pub.beacon_interval

and another one in cfg80211_get_bss where you print out the return value
(just to make sure it's returning the right thing). Maybe also put one
into cfg80211_bss_update where it updates things.

I suspect that some memory is getting overwritten or something. The
embedded struct thing was a bit of a hack.

Also please put a printk into the iwlwifi code and into
net/mac80211/mlme.c where it assigns
	sdata->vif.bss_conf.beacon_int = bss->cbss.beacon_interval;

so that I can see the order this happening.

Thanks,
johannes
