HP Pavilion dv9645ed & linux
Hi, I recently purchased a HP Pavilion dv9645ed laptop and I'm having nothing but problems with it. First thing after i removed the preinstalled Vista i tried to install Ubuntu Gusty. The setup went fine but when I restarted the computer Ubuntu wouldn't start and give me this error:
Code:

After a ton of internet searches I found that my error is a hardware problem:

With MSI disabled in this way, the PCIe bus can only act as a faster PCI bus with hotplug capabilities. This is also true of the Nvidia nForce 560 chipset.
Of course the suggestion from Wikipedia had no effect on my system so I had to recompile the kermel to disable handling of MSI interrupts. Obviously after I started the new kernel nothing worked right anymore including sound and that nice Restricted Drivers Manager. OK so after a lot of more or less complete/useful tutorials and howtos I finaly get almost everything to work on my laptop.
So all was well until I got another weird error:
My keyboard suddenly stops responding without any particular reason. Also if I'm installing/removing packages the process freezes as well Yet my mouse is fully functional and so is the entire GUI. If I try to restart/shutdown the system then it gets to the point of "Will now halt" and then it just stops leaving the laptop running. I have to force it to shutdown keeping the power button pressed for a few seconds.
I tried googling but couldn't find anything useful regarding this particular problem. I'm not even sure of what I should be searching for.
If anyone has any suggestion it would be greatly appreciated. Thanks
