    There is no point in enabling ASPM, because of:

    Can somebody post a dmesg output here? Ideally with and without the custom DSDT? By the way, I'm using neither Bluetooth nor USB Ethernet, but I was experiencing shutdowns nevertheless. Also, my...

    By vanilla kernel I meant kernel downloaded from kernel.org. I am using the DSDT modification for over a week and never experienced a shutdown. And I certainly gave my laptop a hard time. During that...

    What about VT-d and IOMMU? Both deactivated? Maybe it's worth trying vanilla kernel.

    CLARIFICATION:
    IOMMU only influences VT-d, this is not vital to virtualization. You should definitely disable VT-d in the BIOS as well.

    You are right, this parameter is discouraged anyway, albeit I have seen no adverse effects on my machine. I will remove it from my kernel line and the website nontheless.

    Hehe,
    nice yellow bastards are they indeed. Price on the UX31E is quite hefty, so they should think twice before pissing their customers off. :-) Still, a $1500 laptop should not have f*cked up DSDT...

    I'm going to kernel "linux-3.2.1-gentoo-r2", I really don't need to live on the bleeding edge (3.3_rc1). It was working smoothly though. I'm quite curious how this one will fare. Also, it's almost...

    You should turn off VT-d in the BIOS and IOMMU and DMAR in the kernel. Use the GRUB cmd line if you are using a stock kernel. I have disabled support for IOMMU and DMAR in my custom kernel and don't...

    Hi,
    the DSDT table is extracted from BIOS 210, so yes, you need to upgrade to 210 to use the fixed DSDT. Another thing is, that rc6 is unstable with the IOMMU, so you need to disable IOMMU in thr...
