The last three kernel upgrades have all caused my computer to stop booting correctly. In different ways. Re-installing the kernel package fixes it. Awesome.
After an update with a new kernel, my computer got stuck in a reboot loop. Reinstalling the kernel fixed it.
Seriously? This can happen?
I like how old kernels are never removed when you update them, leaving lots of options that nobody uses in the GRUB menu and hundreds of MB of hard disk wasted. It should offer to remove older kernels after you’ve been using the new one successfully for a few weeks/months.
