The dm devices appear to be disks, but they aren't - they're LVM
creations. As such, they're not going to hold a partition table in the
same way as a real disk.

It's arguably a bug that "fdisk -l" even looks - but I'm not sure whether
that's a bug in fdisk or in LVM...

In this context, I wouldn't worry.

What symptoms do you see?

Failing to find disks when booting a new kernel usually means you need to
run mkinitrd - but I'd expect a distro kernel package to come bundled with
something suitable...
