Problem of l4lx_thread kmalloc

[강후영]

Hi, 
I created l4lx_threads by "l4lx_thread_create()". 
But when these threads alloccate some memory by kmalloc(),  fault error always occurs as fallow, 

l4lx | L4RM: [PF] read at 0x999999b0, eip 0042e30a, src E.0B 
l4lx | [E.0] l4rm/lib/src/pagefault.c:78:__unknown_pf(): 
l4lx | unhandled page fault 

What is the problem? 
Is there some size limitation of kmalloc for thease threads? 
I tried to allocate a few KBs. 

Best regards
