I recently acquired new machine with a P4HT processor, unfortunately
when I compiled SMP support into kernel, hell broke off:

According to System.map these symbols are in kernel!

Any way to fix that except building a monolithic kernel without modules?

Did you remember to recompile and re-install all modules?

The SMP modules are different from the corresponding UP modules.
