PCI configuration error on kernel boot.

[Luke Yelavich]

When booting Ubuntu Warty RC1, with linux-image-
2.6.8.1-3-686 2.6.8.1-16 kernel, I get the
following message while the kernel loads:

PCI: Cannot allocate resource region 4 of device

System still runs fine. This did not occur when
originally installing the preview release.

[Matt Zimmerman (mdz)]

Do you have any problems with the system? Or are you only concerned about this
message?

[Luke Yelavich (themuso)]

The system still boots with no problems, but a previous
installation of Ubuntu with the latest kernel didn't show
this message.

[Herbert Xu (herbert-gondor)]

Your lspci result shows that you're running an old kernel with MSI turned on.
Please retest with the latest 2.6.8.1-16 package.

[Herbert Xu (herbert-gondor)]

Nevermind, this turns out to be an ACPI issue.
