Package: lvm2
Severity: critical
Justification: breaks the whole system

I unwittingly ran into bug #288354 today. Creating the snapshot froze my
machine, as described in that bug report.

After a while I rebooted the machine, but it will no longer boot up:

	device-mapper: 4.1.0-ioctl (2003-12-10) initialised: dm@uk.sistina.com
	  Can't expand LV: Snapshot support missing from kernel?
	  2 logical volume(s) in volume group "main" now active
	pivot_root: No sKernel panic: Attempted to kill init!
	uch file or dire ctory
	/sbin/init: 432: cannot open dev/console: No such file

I booted into a recovery system and the various filesystems and volumes
seemed fine:

	rescue:~# lvdisplay

However, when I try to remove the rootbackup snapshot:

	rescue:~# lvremove -v /dev/main/rootbackup
		Using logical volume(s) on command line
	Do you really want to remove active logical volume "rootbackup"? [y/n]: y
		Archiving volume group "main" metadata.
		Found volume group "main"
		Loading main-root-real
		Loading main-rootbackup-cow
		Loading main-rootbackup

At this point, the machine crashes as before. I can still ping it, but
user space seems totally dead.
