Looks like Bug #148003. IMHO, it's a race between udev and cryptsetup (libdevmapper).
I "fixed" it by removing /etc/udev/rules.d/65-dmsetup.rules. This file seems to have been introduced by a recent Ubuntu patch. Presumably there was a good reason for it, but it causes havoc. -- LUKS partition mounted to /dev/mapper, but not to /media https://bugs.launchpad.net/bugs/156285 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
