--- Comment #14 from Igor Rudchenko igor@starrain.org 2012-02-22 16:56:23 --- Commit "PCI: Rework ASPM disable code" added in 3.0.20 and 3.2.25 has worsened the situation. I can't enable ASPM on ThinkPad T60 now even with "pcie_aspm=force" kernel parameter. So radeon is always hot now.
Are you sure it's about ASPM ? My radeon (On a HP laptop) is very hot because of the unimplemented (and/or buggy) power management in the radeon driver!
I can make the temperature lower if I switch to power_profile "low" instead of the "default".

Already tested kernels 3.2.7 and 3.3-rc4 - same problem.
