first of all i must say i am a german linux noob

first of all i've got wlan to work fine

but if i try injection with

aireplay-ng -1 0 -a ...[bssid]... -h ...[mac]... -e [essid] wlan0

i got the message

waiting for beacon frame (BSSID: ....) on channel 11

and the system freezes

so my question is what is wrong there?

i also tried this

h t t p ://trac.aircrack-ng.org/ticket/558

but still the same problem

any ideas?

ok... update...

notebook: asus x56t
Network controller: Atheros AR928X (rev 01)

the errormessage after launching aireplay

Kernel panic - not syncing: Fatal exception in interrupt
any ideas how to fix this?
