Hello guys,
I really don't know what to do. I can't even install a native ubuntu in my
machine. The overall sys performance is awful.
Now, the only way to use the system is using wubi, but with poor performance
and so much noise from the hard drive.
I have a Asus P5K-Premium WI-FI, with a Q6600, 4GB ram and the SAMSUNG HD501LJ .
So, I think I can expect a good performance from my machine :)
I'm using the Jaunty 64bits beta. I tried to use gutsy and intrepid too, with
no good news.
What makes me really confuse and sad is that windows vista/xp runs with awesome
performance, and no noise.
Here is some info:

I also tried to recompile my kernel several times, but with no success too.
If I can help, or run some tests, please let me know.
This problem is really annoying, and based on the above info, it's bothering
many people.
Thanks,
Andre
