Kernel panic was caused by my miss configuring.  I used a Guile module
on reconfigure via GUILE_LOAD_PATH and (use-modles (my-module) in
config.scm.  I guess it's also required after reconfigure, according to
some times getting errors after reconfigure: cannot find my-module.  So
I need to add my-module globally on system.
