did you compiled this kernel by your self?
if yes, than this is no problem:

go into kernel tree and start 'make menuconfig'

once it opened, press 'shift+7', than in the search line copy 
'CONFIG_FUNCTION_TRACE', it will show you where this option is located. 
now just go there and disable that option. recompile and done.
for recompiling the kernel, a always save the '.config' file somewhere 
else, than i remove the kernel tree and extract it again. after it i 
copy the '.config' into the new extracted kernel tree and run 'make 
oldconfig'.
i think there is a faster way to do it, but i don't know how, it works 
this way for me.

cheers,
doc
