kernel hangup

Hi all,

my linux kernel boot correctly, find the filesystem, run startup scripts, shell and then hangup in mm/slab.c in cache_alloc_refill(...) function. The# define CONFIG_DEBUG_SLAB produce on console next messages (repeatedly):

This architecture does not implement dump_stack()

kfree_debugcheck: bad ptr 1148368h.

mismatch in kmem_cache_free: expected cache 011b3348, got 01ffe928

01ffe928 is names_cache.

011b3348 is <NULL>

What is wrong?

my current configuration:

Altera NDK board with NIOSII/f from examples which is included in NIOSII devkit.

Microtronix Linux 1.2 (kernel 2.6.5)

Any help will be appreciated...

Thanks

Holy
