which version are you using, have you tried latest trunk?

Let me hijack this ticket a bit.

Revision r29570 fixes most of the problem that crashes the wifi immediately.

However, sometimes, the above error still appear, as in, appearing in very quick successions (the above occurred over a period in 2 seconds).

I'm not sure if it crashes the wifi or not as I wasn't present at the time the error occurred but 4 hours later, the wifi is still working (with r29561 I had to type 'wifi' to bring it back up).

An update on the issue. r29570 shows no signs of wifi crashing, though the kernel log in this ticket still appears. That's an improvement.

wifi works fine for 5- 6 day, then was stop after that:

i have to disable and re-enable wifi in luci to fix. so i'm waiting for next lock-up.
