Looks like it maybe related to Bug #148003. IMHO, it's a race between udev and cryptsetup (libdevmapper).

Presumably there was a good reason for it, but it causes havoc. -- Can't mount a LUKS volume after unmounting https://bugs.launchpad.net/bugs/154679 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug contact for gnome-volume-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
