Comment 121 for bug 760131

Adding 'pcie_aspm=force' to stock Natty install on a Toshiba L305-S5937 decreased the heat significantly. This laptop is now usable in Natty without literally burning. Battery consumption has also increased from one to about two hours. I have observed no freezing after the latest stable updates. I have not yet tested hard 3d performance, like a game or something.

However, the 2.6.35 regression remains, and it looks like Michael Larabel is the only one telling users what's going on, so we'll have to wait for him.

Even though it is claimed by some this is not a regression, but a feature, obviously a lot of portable computers were devastated by it, so it's absolutely a regression.

@felixcorrales: You have not been told everything.

You can 'pcie_aspm=force' to

ALT-F2 > 'gksu nautilus', press enter > open File System /etc/default/grub file >

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
GRUB_CMDLINE_LINUX=”"

You can add 'pcie_aspm=force' to GRUB_CMDLINE_LINUX_DEFAULT after "splash" within the quotes or GRUB_CMDLINE_LINUX within the quotes. Save, then *******open Terminal and type 'sudo update-grub' without quotes, press enter, wait for it to finish, then reboot the computer. Only then will the command apply to the kernel.*******
