Replying to tqh:
I assume you see cpu spiking on some acpi thread.
The only acpi thread I see is acpi_task and it seems to be idle all the time.

Retested on hrev58607. The battery is still reported as damaged and no percentage is shown, the only thing that changed since is the icon.

I think newer hardware started using some other method than the embedded controller we rely on. Battery status reports require correct locking with embedded controller, and that probably don't work. I assume you see cpu spiking on some acpi thread.
