all tools I tried (vmstat, top, gkrellm) all report 0% cpu usage. Very unlikely to be true :-)
CONFIG_NOHZ_FULL is very likely the culprit, as there are reports of it causing various CPU accounting breakages. Still being debugged upstream.
It's not getting better with rc3 and from what I read CONFIG_NOHZ_FULL is not some kind of killer feature. Could we disable this until it no longer breaks everything and the kitchen sink?
Mike - Do I recall correctly that you have a fix for this? Or could Stefan have the bad hardware you were worried about? -Jeff -- Jeff Mahoney SUSE Labs
