You don't even need oprofile.  Just boot the kernel with profile=2
Then before you reproduce the problem clear the profile counters
with echo > /proc/profile Afterwards read the profile data with 
/usr/sbin/readprofile

This only works for non modular code, if the problem should be in 
some modular driver it won't find it.
