            Bug ID: 233414
           Summary: [PowerPC64] OPTIONS DEBUG_MEMGUARD results in
                    unbootable kernel
           Product: Base System
           Version: CURRENT
          Hardware: powerpc
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: sbruno@FreeBSD.org

In an effort to debug a user-after-free problem, I enabled DEBUG_MEMGUARD to
try and pin this issue down.

Petitboot or OPAL cannot load the kernel after this is enabled and results =
in
no output or messages logged to the console.
