Thanks Michael,

for finding out.

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. Disabling ASPM
and
365: [ 1.236368] pci0000:7f: Requesting ACPI _OSC control (0x1d)
366: [ 1.236371] Unable to assume _OSC PCIe control. Disabling ASPM
