PCI BIOS bug

[Lorenzo Ferrajoli]

As I understood the problem was "fixed" by Fedora (I use FC8 on an  
ASUS MB) adding to the fc8-patched-kernel configuration the following  
entry:

CONFIG_PCI_MMCONFIG_OFF_BY_DEFAULT=y

so when you try to copy fc8 configuration file to a vanilla  
kernel .config (I tried a 2.6.23.1 vanilla kernel) this parameter is  
not recognized: you can make your new kernel, but, if you set ANY in  
PCI configuration, you'll have the message:

PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG.

I suppose that if you set DIRECT (as you can see in a previous  
message on this thread) you can get rid of that bios bug message.  
Moreover I read that updating the bios had not positive effect but  
I'm not yet sure of that.
