Disabling IRQ 11 Error

Hi List, I'm having a very frustrating problem in that after a while, usually when I'm not using the PC I get Linux kernel disabling IRQ 11 and then my wireless card stops working and I have to reboot to get it working again. I have spent most of this evening looking at google etc so see if I can find a solution to this problem, but have been unable to. I have noticed that there is several things using IRQ 11, wlan0, snd and ndiswrapper, Don't know if this is a problem or not. Here is what I have : SuSE 9.2 Pro KDE 3.3.0 Kernel 2.6.8-24.14-Default Linksys WPM54g v4 using ndiswrapper As I said everything works perfect for a while and then I get this error. Any help would be much appreciated. Martin
