Yes, the problem does occur in mainline 4.16 and I have added the requested tag.
If anything, 4.16.1 seems slower than 4.15 release kernel even for no cryptswap. It could be that my disk is too slow for cryptswap, but it did work in 17.10. The obvious work around is not to use cryptswap, of course. ** Changed in: linux (Ubuntu Bionic) Status: Incomplete => Confirmed ** Tags added: kernel-bug-exists-upstream -- 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 email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
