Hi,
the wlan daughterboard on a nintendo wii stopped working with current master.
Building from the v3.4 tag gives me a working device.
I bisected this to:
commit 3a25a8c8b75b430c4f4022918e26fa51d557ecde
Author: Johannes Berg <johannes.berg at intel.com>
The hw queues fail the check in ieee80211_check_queues(). When I hack
that function to always "return 0;" wlan works again.
These 2 printk()s:
