Title:
  Please enable CONFIG_PCIEASPM_DEBUG

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Vivid:
  Fix Committed

Bug description:
  CONFIG_PCIEASPM_DEBUG (which is currently disabled for Ubuntu kernels)
  can be used to enable/disable ASPM settings per PCIE device.
  CONFIG_PCIEASPM (which is enabled for Ubuntu kernels) allows only to
  set global ASPM policy. BIOSes on more machines are buggy and lot of
  times do not configure ASPM for PCIE device property.
  CONFIG_PCIEASPM_DEBUG option allows users or testers to hotfix
  potential bugs in BIOS... That config option only add new sysfs files
  so it should not break anything else in kernel.
