Hi and thanks for taking the time to report this bug. There isn't really enough information here for a developer to confirm this issue is a bug, or to begin working on it, so I am marking this bug Incomplete for now.
Given that the setup you are trying to achieve is rather non-standard, I'm prone to think there is a problem in the setup itself, rather than a bug in Ubuntu. You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community. If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New. ** Changed in: bcache-tools (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878340 Title: Backing device unattaches from caching device when hibernating into a swap file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcache-tools/+bug/1878340/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
