Fixed In Version: kernel-2.6.32-71.27.1.el6 Doc Type: Bug Fix
Doc Text:
Under some circumstances, faulty logic in the system BIOS could report that ASPM (Active State Power Management) was not supported on the system, but leave ASPM enabled on a device. This could lead to AER (Advanced Error Reporting) errors that the kernel was unable to handle. With this update, the kernel proactively disables ASPM on devices when the BIOS reports that ASPM is not supported, safely eliminating the aforementioned issues.
