On this it works
 5.3-STABLE FreeBSD 5.3-STABLE #0: Thu Feb 10 17:38:05 EET 2005     root@it.buh.tecnik93.com:/usr/obj/usr/src/sys/IT53_U  i386
this kernel has ULE

On this it crash
 5.3-STABLE FreeBSD 5.3-STABLE #17: Mon Jan 17 23:40:22 EET 2005     itetcu@it.buh.cameradicommercio.ro:/usr/obj/usr/src/sys/IT53_d  i386
this 4BSD
