PCI BIOS Bug messages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I run Fedora Core 6 on the 'compaq nc6320' laptop. I am using the
'2.6.19.1' kernel.

While booting the kernel, I noticed the following error message:

PCI: BIOS Bug: MCFG area at f8000000 is not E820-reserved
PCI: Not using MMCONFIG.

After some search, I commented out the 'e820_all_mapped()' check in
the 'pci_mmcfg_init()' function. I no longer see this message and MMCONFIG
method seems to be used now.

Is this the right thing to do?

Thanks,
