I've never seen this, nor have I seen other reports of this.
One possibility that comes to mind is that you have a heterogeneous
mismatch of some objectfiles that were compiled with CONFIG_LOCKMETER
and some without. Are you using modules, and were they all consistently
compiled with CONFIG_LOCKMETER and then properly installed? You might
try doing "make mrproper", then "make menuconfig" (or whatever your
favorite technique is) to turn on lockmetering, then "make dep", then
build your kernel and modules and install them.
