Can you try the following patch? http://bu3sch.de/patches/wireless-testing/20080404-1408/patches/010-b43-calibrate-lo-on-demand.patch
This patch is supposed to distribute the calibration bursts over time, so that calibration only happens when it's actually needed. So instead of disabling the MAC every 120 secs and recalibrating the whole calibration tables, we assign a timeout to each calibration value and only recalibrate it if it's a) expired and b) currently used. Recalibration might also happen on TX power adjustment, if the corresponding calibration item is no longer in the cache because it has expired. That actually happens most of the time, but we can live with it, as power adjustment doesn't happen that often and calibration is a _lot_ cheaper. This patch also reduced overall memory consumption by nuking the huge static calibration tables. Disclaimer: The algorithms in this patch are completely redesigned and have nothing in common with how broadcom does the stuff in the proprietary driver. So it's highly experimental and I'm not responsible in case this patch eats your cat. -- Greetings Michael. _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
