We found that this has nothing to do with the timer patches. There is a
scribble in pcie_rootport_aspm_quirk that overwrites ptype_all.

quirk_aspm_offset[GET_INDEX(pdev->device, dev->devfn)]= cap_base + 0x10;

does the evil deed. The array offset calculated by GET_INDEX is out of
bounds.

The definition of GET_INDEX is suspect:

#define GET_INDEX(a, b) (((a - PCI_DEVICE_ID_INTEL_MCH_PA) << 3) + b)

should this not be

#define GET_INDEX(a, b) ((((a) - PCI_DEVICE_ID_INTEL_MCH_PA) << 3) + \
				((b) & 7))

?
