Can you identify the most recent 2.6 kernel akpm> which didn't have this bug? Without powernow! feature, works fine.(I tested every -rc kernel after 2.6.8 for x86_64).

I'm using xserver-xorg at debian,6.8.2-dfsg.1-5 happend OOPS at any process using X any older kernel, but update X to 6.8.2-6, any processes not/with using X got null exception and down when enable powernow! feature :-( What happened?
