Hello, i'm jumping in having the same problem as brendan. I bisected this myself. The offending commit is this one:

At boot, right after I enter my drive encryption password, it kernel panics with the above message. It doesn't even get far enough along in the boot process for syslog to log this panic, so the only info I have is a photo of the panic. In short, I can't boot using the latest artful aardvark kernel, and I have to boot with the latest zesty zapus kernel. :~$ lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 linux-image-4.13.0-16-generic I expect this isn't normal and I should be able to boot with the new kernel, which I can't.
