You are most likely not passing the clock speed from bootloader
correctly. You can set it forcibly in the beginning of ocotea.c, or
else fixup the structure passed between bootloader and kernel so that
both sides match. Doing the latter will fix a lot of other troubles
that you will encounter later on as well. See also:
