[BUG] hang with ath5k

[BUG] hang with ath5k

[Dave Young]

Hi,

2.6.27 + ath5k, while using wpa_supplicant & wpa_gui system hangs
occasionally, keyboard not respond, network stop working.

There's same problem in before kernel version, but I don't know the
first version which introduce it.

The last messege on xconsole is:

disassosiating by local choice

I reproduced it by:

1) run wpa_supplicant
2) ctrl + C
3) goto 1)

dave

It doesn't happen here. How many iterations in average you need to reproduce this?

Is this a regression from 2.6.26?

Hi, I don't think so, There's such problem in 2.6.26 as well.
