Hi, I recently noticed that i have the following error when booting kernel:

PCI: Cannot allocate resource region 0 of device 0000:00:00.0

Everything is working fine, but i still want to know what this is about... I know, If it ain't broke, don't fix it... but, I can't fight with my needs for knowledge :p

This is what dmesg returns (only what we need):



PCI: Cannot allocate resource region 0 of device 0000:00:00.0
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 4x mode
agpgart: Putting AGP V3 device at 0000:02:00.0 into 4x mode


And here's lspci -v:

Is it an AGP problem? Or is it a Host bridge: nVidia Corporation nForce3 Host Bridge problem?

Also, I have AGP 8x... is it working at 8x, or 4x? In the BIOS is configured for 8x...

Thanks!
