@nicholes,

For future reference: I think it's written just about everywhere that you should NEVER uninstall kernel-power using HAM. There's an extra icon in the app list for "Deinstall Kernel-Power", or something to that effect.

Reason is when you just remove kernel-power something (e.g. the standard kernel) has to replace the kernel that has been removed. The app takes care of that (presumably). HAM does not.
