  • The computer is equipped with Peripheral Component Interconnect (PCI) Express Interface slots.
  • Active State Power Management (ASPM) is enabled in the computer’s BIOS setup.
  • The computer is installed with ATI HD3870x2, ATI HD4870x2 hardware, or other hardware that has a PLX Technology Inc. PEX 8647-AB PCI Express switch.

The system may show low graphics performance, and occasionally the system or certain applications may respond slowly or may not respond at all.

RESOLUTION

After you install this hotfix, the ASPM functionality is disabled for the device that is affected.
