Random freezes in Kubuntu

[Eric Marquez]

@Steven:
Thanks for your answer. And thanks for the tip, I'll try it. Where exactly should I place that line (pci=nomsi )? do you mean in the Grub menu?

@Ric:
 Thanks for your answer... your approach is interesting but, if the problem should be Power Supply, why doesn't it happen in Windows (remember I have a dual boot), and why didn't it happen when I had kde3?

@Lamanary Ramos de Pina:
 Lamanary: thanks for the link. It's very interesting and it's the first time I see this problem categorized as Bug. All the descriptions of the problem are not exactly as mine, so I'm not sure that's exactly my case, but anyway I'll subscribe to that bug and try to participate. I'll do anything to solve this problem.


 Greetings,
 Eric.

If you have an nVidia chip on your motherboard or an nVidia Gforce video card, 
especially if it is a high end chip on the board, you may have to add 
pci=nomsi to your boot instructions.  It fixed my problem.  My board chip is an 
nVidia 780a and my video card is 9600 G force nVidia.  I don't like to give 
any advice, due to my inexperience, however, it cured my problem, and it is 
hard not to at least try to help, after all you have done for me.
