hi all: recently, i met a odd problem and i need your help . when i run "make menuconfig" , the system output a .config for me , it's image is ok to use. the .config is like this: # # Automatically generated by make menuconfig: don't edit #

CONFIG_CONTIGUOUS_PAGE_ALLOC is not set then i modified the config by again running "make menuconfig", the system output .config for me again, but this time the image can't run , it report a BUG in slab.c in kmem_cache_creat function ,exactly live at this: down(&cache_chain_sem) { struct list_head *p; list_for_each(p,&cache_chain){ kmem_cache_t *pc = list_entry(p,kmem_cache_t,next); if(!strcmp(pc->name,name)) BUG(); } } i don't know why, and wonder what's the difference between the two .config that affect the image? the modified .config is like this : #
