I see that your disks are not of equal size - I have seen one other
report of problems with the RAID-5 driver (in reaidreconf - not the
kernel RAID-5 driver) related to disks of different sizes.

That's profiling output - because raidreconf (for some reason) was
compiled with the -pg switch for gcc.
You can run "gprof raidreconf" and see which routines take up the most
CPU time :)
