Some good and bad news: I have been testing this in a running Gnome 3 environment. I decided to start testing on console. On console, all kernels seem to fail using crypt swap. This suggests to me that failure must depend on current memory usage, dirty ratio, or some such runtime condition.
However, the good news, I have kernel messages on console. I'm attaching a screen shot, since none of them get written to syslog. A typical message is: task dm_write:xxx blocked for more than 120 seconds There are no problems when not using dm_crypt for swap, i.e. 'normal' swap. ** Attachment added: "Screenshot of console error messages during hang" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1762468/+attachment/5112862/+files/hang.png -- 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
