ath5k in AP mode works!! (but sometimes with an oops, and a panic)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



First of all great work! AP mode works almost flawlessly.

The only things I encounter:
- At hostapd shutdown the kernel panics frequently, freezing up the system.
- At startup I encounter the trace below.
- In between the WPA2 sessions seem to work flawlessly.

Hope this helps.
