I am not sure if anyone from Ubuntu will even respond here, but I checked upstream code and provided logs (btw thanks for them, very usefull here).
What happens here is: - system is fully udev managed, both userspace and kernel are recent enough - according to logs, something during "udev event" acknowledge fails and libdevmapper takes old compatible path (trying to create/remove link in /dev/ itself) and also decrementing cookie semaphore. - unfortunately, the event _was_ triggerred and dmsetup udevcomplete called and because both udev and libdevmapper decrements the semaphore, the second call fails with the message above. I think the reason is in kernel (kernel do not annonce for some that uvent was sent) but I was not able to reproduce this. If you have some way how to reproduce it reliably, please let me know... (The bug is not critical, the operation itself finishes correctly.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719388 Title: semop failed for cookie 0xd4d09ef: incorrect semaphore state during luksOpen -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
