It seems that cryptswap is working correctly on 17.10 with the kernel 4.13.0-36-generic on a different machine using the same test as described above. I tried the same kernel (4.13.0-36) on 18.04 (machine used in original post) and it still fails. Of course, I checked that the swap appears in /proc/meminfo. Hope this provides a clue.
[FYI, I'm using 4.13.0-36 rather than 4.13.0-38 because of a bad firmware interaction with 4.13.0-37 and 4.13.0-38 that results in CPU lockups] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762468 Title: Cryptoswap not working in Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1762468/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
