"PCI: Cannot allocate resource region 4 of device 0:00:

[brujo66]

Hi,

During the boot process, the machine shows something like that:

"PCI: Cannot allocate resource region 4 of device 0000:00:02.1"

Anybody can tell me reason of this message?

Theres no problem with the system...everything runs perfectly, but this message sounds bad.

Any help will be thankful

Is this during the autodetect phase of the LiveCD or when booting a configured Gentoo installation ?

It may be merely a message that the BIOS's PnP detection is slightly different from what Linux thinks of it, or maybe the PCI card reports a resource range that it doesn't actually use - quite a few possibilities.
As long as there are no actual errors I wouldn't worry overmuch - PCI detection can be pretty convoluted at times.

If you're using the nvidia-kernel drivers it may be related to this:

Hello,

First, thanks a lot.

Second, sorry me. I didnt give you all information. I try to explain here.

This message is shown when the installed system boots up. Not when the LiveCD is booting.

I have a Radeon graphic card, not a Nvidia.

Also I recive the next message during the boot:

"mtrr: no MTRR for f0000000, 10000000 found"

I have supposed that this message could be generated by an incorrect instalation of the ATI drivers, maybe. I dont know.

Thanks a lot again.

No, the mtrr message is processor-related (Memory Type Range Registers, to be exact - I'm pretty sure you didn't want to know that )

As for the PCI error message, if you Google for it you will find quite a few occurences but very few actual explanations - so maybe it's best to ignore it if your system behaves normally...
