I dunno if kmemleak is > spurious or not. As always, any ideas? I can't seem to boot a kmemleak kernel myself. But there were a number of fixes to kmemleak recently to track memory allocated in ieee80211_register_hw, IIRC -- so it would be good to know if this persists with all the latest fixes. As always, no ideas :( I'm guessing nothing in .31-rc has magically fixed any problems? I still say it's some kind of race condition made worse by the eeepc performance, but unless I can find one or replicate it with introduced load, I'm afraid I'm stumped. (Well, I guess we can always go off and rewrite the rx loop without the circular terminator and see how well that works on your HW.) -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
