The motherboard. More specifically, the BIOS. It is only saying that ASPM ( power saving mode for the pcie bus when it is idle ) is being disabled as a result, so just ignore it.

That's to say,it's not important? Because my server freezes randomly and its monitor turns to black screen. and I have to restart manually Then I suspects other errors which I saw kernel:udev-fallback-graphics main process terminated with status 1 kernel: init: failsafe main process killed by TERM signal load fallback graphics devices[fail] For this second error I reinstalled graphics card After that the machine hasn't been down yet 02:00.0 VGA compatible controller nVidiaCorporationG98GeForce 8400 GS rev a1 prog-if 00 VGA controller I have 2 nic cards realtech onboard,intel Whatcan be problem –  Yavuz Maslak Dec 9 '11 at 22:37
    
@YavuzMaslak I suggest asking a new question with the exact problem. –  htorque Dec 24 '11 at 15:04

The kernel is reporting that the firmware has refused to pass control of PCIe functionality to the kernel. _OSC is an ACPI control method that the kernel uses to see if the firmware (BIOS) will allow it to control PCIe Active State Power Management (amongst other things).

This is just a warning message and not a bug.
