Package: linux-image-4.9.0-2-rt-amd64-unsigned Version: 4.9.13-1
Dear maintainer, the Debian kernels are currently built without the CONFIG_LATENCYTOP option: $ grep LATENCYTOP /boot/config-4.9.0-2-* /boot/config-4.9.0-2-amd64:# CONFIG_LATENCYTOP is not set /boot/config-4.9.0-2-rt-amd64:# CONFIG_LATENCYTOP is not set The result is this: # latencytop mount: none is already mounted or /sys/kernel/debug busy Please enable the CONFIG_LATENCYTOP configuration in your kernel. Exiting... So could you please enable this option? -- Laurent.
