Got it now. My Unix/Linux twisted mind took the [01] in the file name as a slick indication that there were two pictures, one with 0 there and one with 1 there. It never occurred to me that it was literally the file name ;-) :-( Anyway, I wonder if this particular oops is fixed by commit: 20ed3166c84d145589a89d8cde12aa32cf2d17f4 mac80211/rt2x00: add ieee80211_tx_status_ni() which got into Linus' tree after 2.6.37-rc7 but is part of 2.6.37 final. It looks a lot like the symptoms that that patch was fixing. --- Gertjan.
