Do you have an idea which patch may have This one definitely fixes it: http://patchwork.ozlabs.org/patch/55643/ (Herbert Xu: udp: Fix bogus UFO packet generation) The patch works with 2.6.32.24 too - it should probably be backported to 2.6.32.x. -- Leszek "Tygrys" Urbanski, SCSA, SCNA "Unix-to-Unix Copy Program;" said PDP-1.
