Note that this also applies if your swap is on ZFS. Ubuntu will attempt to use it automatically and cause a 30 second delay as the swap partition will not be available during early boot. Ie.
I: The initramfs will attempt to resume from /dev/zd0 I: (UUID=a0c4e220-8b9f-447b-b2e2-d2abeb2f6c39) I: Set the RESUME variable to override this. and Aug 2 14:58:00 taisph-enodatio kernel: [ 3.822995] Btrfs loaded, crc32c=crc32c-intel Aug 2 14:58:00 taisph-enodatio kernel: [ 35.038644] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null) Setting RESUME=none is currently necessary to work around this. Tested with initramfs-tools 0.130ubuntu3.1. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1771962 Title: hanging at boot for about 30 seconds since upgrade to bionic Status in initramfs-tools package in Ubuntu: Fix Released Status in initramfs-tools source package in Bionic: Fix Released Bug description: [SRU Justification] A regression in initramfs-tools causes it to autogenerate config in the initramfs saying to resume from any available swap devices, even if the swap device is ephemeral (i.e. swap encrypted with a random key). This adds an inappropriate 30-second boot delay to any system with randomly-crypted swap, which includes any system that was installed with encrypted home directories in earlier releases. [Test case] 1. Install the ecryptfs-utils package. 2. Enable encrypted swap by running 'sudo ecryptfs-setup-swap'. 3. Run 'update-initramfs -u' to regenerate the initramfs. 4. Reboot. 5. Verify that dmesg shows a 30-second delay before mounting the root filesystem. 6. Install initramfs-tools from bionic-proposed. 7. Reboot. 8. Verify that dmesg no longer shows a 30-second delay before mounting the root filesystem. [Regression potential] This makes changes to shell scripts, and shell is a perilous language. An unnoticed bug could cause all initramfs generation, and thus all kernel installation, to fail for some users. A regression could also cause a user to lose hiberation support that they currently have. [Original description] Since upgrade to Bionic ubuntu is hanging at boot for about 30s. A `dmesg` shows ``` [ 3.407230] clocksource: Switched to clocksource tsc [ 34.632583] EXT4-fs (sda2): mounted filesystem with ordered data mode. Opts: (null) ``` This is 100% reproducable and is always 30s minimum. I do not know in which package to report this properly – please excuse me.
