I know tmpfs(5) is experimental on FreeBSD, but it seems to be enabled
for ports-mgmt/tinderbox-devel, which probably not too coincidentally
had just started a build before the machine panic'd.

I have dmesg from the last boot available here:

The machine runs a full ZFS setup, with a custom kernel; KERNCONF is
available here:

Any advice on how I can help provide further information would be

Best regards,
