Check `dmsetup udevcookies` output. lvcreate may be waiting for udev process which timed out - check the syslog. You can forcefully complete a transaction by `dmsetup udevcomplete <cookie>`

Hi
1. lvm2 should not freeze - it would be some horrible bug.
2. You can't kill any userspace app which is blocked in an uninterruptible
kernel function - kill always wait till it gets to signal handler (i.e. you
are opening&reading suspended device might be one such operation)
3. You need to tell us more about what you are doing - as without this there
is no way to give meaningful help.
