The PIO mode doesn't work for me at all. The logs after automatic switching
are identical to those of coldbooting b43 with pio=1. 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).
