Description ZyX 2013-03-24 09:32:10 UTC 
When trying to run latencytop it claims it cannot run without CONFIG_LATENCYTOP enabled. But unlike message from mount (“mount: none is already mounted or /sys/kernel/debug busy”) this message shows only 40 % of time (5 times out of 12 runs).

As installed latencytop fails to display correct error message it would be better if latencytop failed at the build time then.

Please post your `emerge --info sys-process/latencytop' output in a comment.
