hmm, so the SNR of b43 and p54 are comparable?

good...

reason 7 must be:
WLAN_REASON_CLASS3_FRAME_FROM_NONASSOC_STA

and class 3 frames are (according to 802.11-2007 11.3.c)
	- "normal" data frames
	(- some MLMEs - probably not relevant )
	- control frame:
		=> especially: Power Save Poll.

your log doesn't hold any records about a disassoc event from the AP.
so, my first guess would be that you're hitting yet another
power saving related issue.  And as far as I know b43 does not do that yet.
So, can you please give the device another go without ps?

(BTW: mac80211 prints a debug text (if enabled in kconfig),
 whenever the device goes or leaves the hibernation mode...
 do you see any of those too?)

does the time between reassoc & _deauth_ vary, or is it always ~24 secs?)
do you experience this behavior on an idle or loaded link?
