    If you install Ubuntu on 11.04, or other distros with latest Linux kernel, or if you update to latest kernel (2.6.38 and +), you might experience freezes during or after booting the system. If system boots without freezing, your wired connection is going up and down constantly. This is related to either power management of the PCIe bus bug, BIOS issues or most possibly a driver (JMicron) related bug. The fix for this is to add 'pcie_aspm=off' to your kernel boot options.

    On Ubuntu is in the /etc/default/grub file, it should look like this:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off".

    On other systems, find the kernel boot options and add 'pcie_aspm=off' to it. I am guessing that the NP8150 and NP8170 are also susceptible to this problem as well.

    Happy Linuxing!

    10.10 works fine for me but 11.04 crashes with or without disabling aspm.

    If you must run those kernels, you could do it in VMWare. Thanks for the quick fix though!
