LOCKDEP_SUPPORT mean that LOCKDEP can be enabled on cpu architecture
for which kernel is build. To enable it you have to use "make menuconfig"
and mark up "Kernel hacking ---> Lock debugging: prove locking correctness"
After that CONFIG_LOCKDEP=y should show up in .config.

Again, lockdep should print more information and allow to debug
this easly.
