ACPI failure after recent upgrade

Today I've upgraded mkinitcpio to 0.6 and removed klibc. But on next start ACPI failed with following messages, according to dmesg:

... [registered some buttons etc] ...

... [some more messages like these] ...

When system up, battery monitor (and files in /proc/acpi) says that no battery is present (see italic messages, theoretically battery is present), but DPMS and suspend work.

Is there any solution apart from downgrading? It's a big problem for me, cause I'm often using my laptop on batteries.

Re: ACPI failure after recent upgrade

Looks like some magic (i.e., simple full system restart) helped. After that ACPI looks normal. Some errors still are in dmesg, but seemingly not critical.
