Subject: WARNING: at arch/x86/kernel/hpet.c:390


Does this ring a bell for anyone ?

I see this on a 2.6.31.1 based kernel...
Arch is x86_64
Distro: Mandriva Cooker

It also happends if I patch in the full ACPICA 20090903 as of 2.6.32-rc1 
+ the ec fix

asus_atk0110 is not loaded...


System is a Core-i7 860 on a Asus P7P55D DeLuxe
