Hi,
Just noticed today, but they perhaps exist for quite some time. I'm
recording ACPI errors on my hp workstation zx6000 when booting 3.9 and
3.10 kernels (didn't try earlier kernels):
[ 25.509388] libata version 3.00 loaded.
[ 25.514781] ACPI Error: [LBAS] Namespace lookup failure,
AE_ALREADY_EXISTS (20130328/dswload2-330)
[ 25.514884] ACPI Exception: AE_ALREADY_EXISTS, During name

[ 25.514965] ACPI Error: Method parse/execution failed [\LBA_.PRT_] (Node e000

[ 25.515429] tg3 0000:20:02.0: can't derive routing for PCI INT A

[ 25.630678] ACPI: Marking method PRT_ as Serialized because of

Can they be safely ignored? How to read them to find which devices
they refer to?
Google can find references of identical errors on other arches too.
Does it mean that there's nothing that can be done to fix them? On
some occurences, these errors were caused by kernel misconfiguration.
Thanks,
Émeric
