That could be a reason alright -- particularly if a kernel upgrade was
happening at that time.  You need to be careful not to reboot in the middle
of upgrades, particularly involving the kernel.

Very early in the boot process you should see a grub message where you can
press ESC to get a boot menu.  You may be able to choose an old kernel
which will boot up or perhaps choose the rescue kernel which will get you
up to a command line.

To finish off an interrupted upgrade, you probably need to do: 

	sudo dpkg --configure -a
