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.
