I can't tell whether this is an ACPI problem. These messages are from
pci_enable_device() and pci_disable_device(). So it looks like you're
seeing an enable/disable pair every 124 seconds.
This could be a problem somewhere in iwl3945_mac_start() that causes us
to turn around and disable the device immediately. Most of the problems
there have IWL_ERROR() messages associated with them, and you apparently
aren't seeing those.
