beaglebone boot errors

Got my Beaglebone today and after a fashion I managed to get the serial working. However there are errors during the boot process of which the unable to set voltage seem a little iffy to me. Are these normal?

Uncompressing Linux... done, booting the kernel.

These are normal.
