Odd...I'm not even sure how one gets to call scnprintf from ieee80211_sta_work... Is this happening a lot? What sort of network configuration do you have? What type of encryption?
This happened one of the 3 or 4 times I booted 0.13 (running 0.17 now). I have Thinkpad X60 sitting about 1 foot from standard Linksys WRT54 type router. I am also within "shouting range" of GoogleWifi (and GoogleWiFiSecure). My network is WPA2 personal, TKIP+AES. That what you need? More?

I see this (attached) on an F9 box with kernel 2.6.26-0.30.rc3.git6.fc10.x86_64. I have absolutely no firmware in /lib/firmware, nor for my saa7146- neither p54-/prism54 cards installed.

Does this problem persist with current rawhide kernels?
Haven't seen this since the date of the report.
