First, these are printed messages with showpfexc=1

l4lx | unhandled page fault
----------------------------------------------------------------------------------------------
10.02 is l4lx.main, 10.03 is l4lx.server and 10.04 is l4lx.timer.i0. PC 
0x00446f79 is kmem_cache_free (in mm/slab.c). As I know, that function 
is called by only arch_setup_additional_pages (in 
kernel/arch-i386/sysenter.c) at the L4 architecture specific parts 
(arch/l4).
I cannot build my fiasco kernel with debugging symbols. How can I do 
that? My kernel configuration is attached.
