WLAN-Card lockup & noises - whats wrong here?

Hi guys.
I am using madwifi-ng wlan drivers and my card is working perfectly - but sometimes…

My card disconnects from the internet and it is trying to reconecct, making weird noises. The following is a snipped of the dmesg output: Mozilla Pastebin - collaborative debugging tool
I’ve already re-installed my drivers multiple times, but these lockups still occur on a random basis. Any help is very welcome. :stuck_out_tongue:

UPDATE:

I just wanted you guys to know that I´ve upgraded to the latest KDE 4.2 yesterday and didn´t hace that problem in 18 hours.
If it occurs again, I´ll state it here - for everyone else that might experience the same issue, upgrading might be a solution.

So long,
TheMask.
