@Miroslav,
Thanks for the ACPI data, it was most helpful to bring some insight.
the IA-PC boot flags does state that "PCIe ASPM is not supported":
[0x06d 0109 2] IA-PC Boot Flags (see below): 0x0000
Legacy Devices Supported (V2): 0x0
8042 present on ports 60/64 (V2): 0x0
VGA Not Present (V4): 0x0
MSI Not Supported (V4): 0x0
PCIe ASPM Not supported (V4): 0x0
and this apparently is what Windows 7 seems to follow
(http://www.microsoft.com/whdc/system/bus/pci/aspm.mspx). So it
appears that the Linux aspm driver is not taking this advice into
consideration and hence we get the problem. Disabling ASPM via the boot
option "pcie_aspm=off" hence makes sense. I will open a discussion with
the Intel developers and see what they make of this.
