 As stated in kern/52995 (duplicate pr) and in the photos linked to in
 this PR, the kernel panics on efi_getsystbl() when booting on a Mac.
 
 I recompiled a kernel with options DDB_COMMANDONENTER="bt" set & tried
 booting it on a white late 2009 Macbook (mentioned in pr 52995).
 System panicked as expected and I now have a backtrace.
