When I custom compile kernel-2.6.11-1.8_FC3 i get these error messages.
BUG: using smp_processor_id() in preemptible [00000001] code: 
cons.saver/3644
caller is load_elf_binary+0xabe/0xd60. I am send along log off dmesesg, 
patching and building off this custom kernel along with .config. These 
error messages was log before starting X and the kernel was untainted. I 
believe this is an bug with the interaction between exce-shield and 
preemtiv. It appeared in Linux 2.6.11, and was to present in kernel 2.6.10.
