I updated again this morning and installed the latest 4.13.0-36-generic kernel. Unfortunately it still panics on boot. I've attached another slo-mo video. ** Attachment added: "Slo-mo video of failing boot of 4.13.0-36-generic"

Thanks for the suggestion @kaihengfeng. I installed linux-generic- hwe-16.04-edge, which gave me a working 4.15.0-23-generic after a reboot. The log from 4.13.0-45 failed at this point: [2.444002] DMAR-IR: IOAPIC id 10 under DRHD base 0xdfffe000 IOMMU 0 [2.52] DMAR-IR: IOAPIC id 9

@jsalisbury Thanks, I followed the instructions and tried booting 4.13.0-30-generic. I still get a kernel panic. I've attached a screenshot from grub with the kernel version visible, and a screenshot of the panic. Thanks ** Attachment added: "grub screenshot"
