https://bugzilla.kernel.org/show_bug.cgi?id=29842 --- Comment #14 from Igor Rudchenko <igor@xxxxxxxxxxxx> 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. 3.2.4 kernel: # dmesg | grep ASPM [ 0.000000] PCIe ASPM is forcibly enabled [ 0.161612] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it [ 3.612673] e1000e 0000:02:00.0: Disabling ASPM L0s L1 # lspci -vv -s 01:00.0 | grep ASPM LnkCap: Port #0, Speed 2.5GT/s, Width x16, ASPM L0s L1, Latency L0 <64ns, L1 <1us LnkCtl: ASPM L0s L1 Enabled; RCB 64 bytes Disabled- Retrain- CommClk+ # cat /proc/acpi/ibm/thermal temperatures: 49 41 37 68 36 -128 33 -128 42 54 55 -128 -128 -128 -128 -128 3.2.5 kernel: # dmesg | grep ASPM [ 0.000000] PCIe ASPM is forcibly enabled [ 0.161614] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it [ 3.523647] e1000e 0000:02:00.0: Disabling ASPM L0s L1 # lspci -vv -s 01:00.0 | grep ASPM LnkCap: Port #0, Speed 2.5GT/s, Width x16, ASPM L0s L1, Latency L0 <64ns, L1 <1us LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- Retrain- CommClk+ # cat /proc/acpi/ibm/thermal temperatures: 51 41 37 72 36 -128 33 -128 43 55 59 -128 -128 -128 -128 -128 Already tested kernels 3.2.7 and 3.3-rc4 - same problem. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
