On a HP 7 pavillion laptop, I tried your solution with "pcie_aspm=force", but is it possible, that aspm is switched off afterwards? here my dmesg-lines: 153: [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.39-0-generic root=UUID=c.. ro pcie_aspm=force 154: [ 0.000000] PCIe ASPM is forcedly enabled but later: 223: [ 0.805341] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it and 357: [ 1.232560] Unable to assume _OSC PCIe control.
