acpi_alloc_wakeup_handler: can't alloc wake memory and ACPI's *** Warning

[Won De Erick]

Hello All,

I just observed the following messages, and attracted my attention. I've seen the following link, but I'm confused how to start with.

I should want to begin understanding why these had occurred.

My box is an IBM x343, with 2G memory. The FreeBSD is just installed in a 512MB-compact flash card with no SWAP partition in it.

Are those harmful?

Any explanation and help pls. to solve this?
