PCI: Cannot allocate resource region

Good morning, i've some error during boot:

[ 15.742871] PCI: Cannot allocate resource region 7 of bridge 0000:00:06.0
[ 15.742922] PCI: Cannot allocate resource region 8 of bridge 0000:00:06.0

[ 15.743017] PCI: Cannot allocate resource region 8 of bridge 0000:00:07.0

My pc seems to o well even if there are these segnalation. My machine is an Acer Aspire 3022WLMI with ati Mobility Radeon X600.

I post you the output of the command dmesg | grep PCI
