This behavior begins as soon as the kernel is loaded. I bisected the problem to: commit 9d8888c2a214aece2494a49e699a097c2ba9498b Author: Hans Rosenfeld Date: Wed Jul 28 19:09:31 2010 +0200 x86, cpu: Clean up AMD erratum 400 workaround Remove check_c1e_idle() and use the new AMD errata checking framework instead.
