You really don't want to do that... 1.1 is well broken.

The Debian packages should be fine. Plenty of other people are using them.
Can you tell which command is issued the illegal ioctl ? It could be that the
LVM device has a wrong major/minor or something else has take the LVM
major/minor device number, because those are /not/ LVM ioctl numbers.
If you can determine what command is issuing those odd ioctls then you're
probably half-way to finding the culprit.
