It didn't change a single bit since my first pr more than a year ago. The difference nowadays is: it doesn't throw a panic, instead it loses the connection and if I try to /etc/rc.d/netif restart then the panic occures.

I'm using OpenBSD 4.5 on the same laptop (it has got Intel 5000 Wifi) and don't have a single failure with it (rum). Btw. the problem persists with FreeBSD 8.0 (i386) too.




>How-To-Repeat:
1. use the network connection (together with WPA encryption via wpa_supplicant)
2. wait some minutes -> connection lost
3. /etc/rc.d/netif restart -> wait some seconds -> et voila: panic
