Here's a screenshot of the panic: https://bz-attachments.freebsd.org/attachment.cgi?id=226185 (blurry since I took it on the plane) The bug is here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256915 If I use an older kernel (which I'm doing for now), it works fine. If I use the memstick USB, it crashes with the same panic. I initially thought it was commit ddfc9c4c59e2ea4871100d8c076adffe3af8ff21, but even when I reverted to one before the said commit, it still panicked with the same error. I don't see any changes to vmd(8), so changes to some other PC subsystem (PCI/ACPI/x86/NVMe/etc.) after commit ab6d05336caaa10ae315f81534851e3764a8660c (current kernel commit) must have caused the error. -Neel (nc@)
