It's running Ubuntu 16.04 with the linux-image-generic-hwe-16.04-edge packages installed. The root partition consists of a simple ext4 filesystem on /dev/sda1, which is on the RAID array There is a more complex secondary mount involving mdraid and bcache intended to be mounted at /srv - but we're seeing problems before that comes into play. Booting into the last 4.13 kernel (4.13.0-39-generic) works fine. Booting into the latest 4.15 kernel (4.15.0-15-generic) results in the root device not being found, and a stacktrace before an initramfs prompt: https://pastebin.ubuntu.com/p/JnTXQ5YP9W/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766770/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
