Same with loading it after wl. The dmesg is attached (that's with plain wpa_supplicant, no NM interfering). Reloading b43 without pio=1 makes it work (to clarify: coldboot -> b43 pio=1 -> b43 -- works; coldboot -> b43 -> Fatal error -> rmmod b43 -> modprobe b43 fails immediately). -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercerpav at gmail.com -------------- next part -------------- A non-text attachment was scrubbed...
