    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:

    After a ton of internet searches I found that my error is a hardware problem:
    Quote Originally Posted by Wikipedia
    AHCI controller does not work on AMD/ATI RS400-200 and RS480 HBA when MSI is enabled due to a hardware error. In order for AHCI to work users must provide the "pci=nomsi" kernel boot parameter. 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

    Well, I've installed the latest kernel ( and still no result. I'm really running out of options.

    Have you tried any other distros?

    I've heard some say that Sabayon works out of the box on lots of laptops.

    Wel, yes, l I have tried Ubuntu, Fedora, Debian, Kanotix and they all failed.

    Slackware and openSUSE worked though.

    Using suse now. Hasn't crashed yet.

    FWIW, on any laptop I have ever had, I usually just find out what hardware it has, and compile my own kernel for whatever distro I use. That way, I have control over what is loaded, and I know what is in my laptop.

    You just have to make sure you include the critical stuff, and then you can go from there.

    Also, if I plan on running linux on a laptop, I will do a lot of homework ahead of time to make sure what I want will run. I have a HP dv2000t laptop with the Intel C2D in it, and it has an intel chipset. Everything on the laptop except for the 56k modem works on it.

    Sorry I can't help you more.

    Hm... Ozzi, wanna give my guide a shot? The only differences between our laptops should be screen size and your graphics card (which should use the same driver anyway)
    Ubuntu on DV6636NR - Ubuntu Forums

    Edit: I mean if you still wanna try Ubuntu. Keep going with Suse if it's workin.
