This "spamming" isn't a problem using the GPL driver thanks to its=20 hysterisis and delays. =46rom my own investigations into the LMAC sources, that event is=20 triggered by an internal LMAC timer if it hasn't received a beacon at=20 all in that time. Disabling powersave operation makes the problem go=20 away entirely, so I suspect what's happening is that the LMAC is=20 consistently waking up a little too late (or going back to sleep too=20 early) to hear the beacons. My guess is that the LMAC is pushing its powersaving margins too close. > Btw. how old is the fw bin you have? I'm using WSM395 currently, dated June 18 2012.
