Answering #102:

Edit /etc/default/grub as root and add "pcie_aspm=force" in the string GRUB_CMDLINE_LINUX_DEFAULT.
After that run "sudo update-grub" and reboot.

Answering #104, and completing #105:

If you find something like

[ 0.000000] PCIe ASPM is forcedly enabled

in dmesg output it should be enabled. You can disregard the next message

[ 0.775371] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it

ASPM is enabled.

I am testing in my computer now and the option seems to make a real difference in may machine (Dell Latitude E6410).
