[Virtual-pkg-base-maintainers] Bug#668445: base: Acpi error during system boot

[marcin]

Package: base
Severity: minor

I get an error message while my system boots. 
/var/log/messages shows:

Apr 11 21:51:49 debian kernel: [    0.221948] PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
Apr 11 21:51:49 debian kernel: [    0.223627] ACPI Error: [CAPB] Namespace lookup failure, AE_ALREADY_EXISTS (20110623/dsfield-143)
Apr 11 21:51:49 debian kernel: [    0.223643] ACPI Error: Method parse/execution failed [\_SB_.PCI0._OSC] (Node f5c3c2f0), AE_ALREADY_EXISTS (20110623/psparse-536)
Apr 11 21:51:49 debian kernel: [    0.223663] ACPI: Marking method _OSC as Serialized because of AE_ALREADY_EXISTS error

I have no idea what this is all about because I am not an IT specialist.
