Debug: sleeping function called from invalid context at mm/slab.c:1856

Hi,

Probably this is a known issue, and might be I should send this message to the
ACPI list, but I tought that considering the current state of the linux kernel
might be someone could be interested in this.

I'm getting this message about every 10 secconds. It seems to be a debug
warning, but it's annoying.
