All these warnings are likely to be the fault of os-prober which runs
during kernel upgrades.

Aha! Bug #788062 (os-prober corrupts LVs/partitions while being mounted inside a VM) seems to be related to the issue I'm having. The scenario of that bug involves update-grub inside a VM, which is also what happens in my case through the kernel installation scripts.
