Hmmm,

In arch/i386/kernel/i386_ksyms.c it states:

#ifdef CONFIG_SMP
extern void FASTCALL( __write_lock_failed(rwlock_t *rw));
extern void FASTCALL( __read_lock_failed(rwlock_t *rw));
#endif

#ifdef CONFIG_SMP
<snip>
EXPORT_SYMBOL(kernel_flag_cacheline);
<snip>
EXPORT_SYMBOL_NOVERS(__write_lock_failed);
EXPORT_SYMBOL_NOVERS(__read_lock_failed);
<snip>
#endif

It would seem that these functions are used in your code, even if it is not 
SMP. ?? This may be a bug in Fedora's version of the 2.4 code. It could also 
mean that you have a strange combination of configure options that are 
causing SMP to be defined somewhere.

Is it possible that you could compile an SMP kernel? I am sure that this 
would work.
