Christian,
I've been working with b43 of late and had not run p54usb until I
tested the rfkill code earlier today. Now I'm getting
deauthentications with reason=7 that I did not get with b43 using the
same AP in roughly the same geometric relationship.
I don't know if this is a regression, or not. The current kernel is
2.6.31-rc5-wl. I'll boot 2.6.30-wl to test if the older one is OK.
The logged data below shows nothing but the timing of the disconnects.
Larry

yeah, b43 definitely needs the attention.
The powersave default mode should be back to "off" for p54, due to:
"[PATCH] cfg80211: allow driver to override PS default".
so, no need to revert the psm patch again.

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?

Actually that was with wl1251. It was a bug in the driver, I'll send a
patch within few days.

Not only reviewing the code, but updating the specs and doing the RE
work. No, I have no further info. Mine have been on a Linksys AP.

Once I got that debug mode set with PS enabled, I still got the deauth
events, but no messages from mac80211. I may not have had the debug
value set correctly. Turning off CONFIG_CFG80211_DEFAULT_PS stopped
the messages, thus it certainly looks like a power saving event.

Any news regarding that dump?
Or are you too busy reviewing b43's LP code? :)
It looks like more drivers are affected.
- Luis reported some deauth (reasons=7) for ath9k with a cisco ap.
- Kalle has the same issues with wl1271 with a ?Zyxel? AP.
