I've mentioned this before..but I have a patch that works around this problem: I had merge issues, so now it's two patches until I have time to clean up my tree: http://dmz2.candelatech.com/git/gitweb.cgi?p=linux-3.14.dev.y/.git;a=commit;h=579035d4b2b7110d67ff451e728709f5b2510ca0 http://dmz2.candelatech.com/git/gitweb.cgi?p=linux-3.14.dev.y/.git;a=commit;h=ae6f95e8a35578e0668e47becb053b29009eec9a I suspect this may cause memory leaks, as a test that causes these work-arounds to hit often will run out of memory after a few days (200+ station vifs constantly doing traffic). Could be lots of other code of course, and kmemleak shows no leaks, so I'm at a loss on the mem leak issue. If you can, try patching these in and see if that works around your tx hang problem. I'd love to have a better fix, btw. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
