Thank you very much!
Ok, one must say, however, that this patch is a tradeoff. It will reallocate all the data and move it around. Of course, that won't help your battery and stuff, as it wastes a certain amount of CPU cycles. :) But it's great that it works. Thanks for testing. Did you also test an x86_64 kernel _without_ this patch? I'd be very interested whether this works or not. -- Greetings Michael. _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
