            Bug ID: 225181
           Summary: SLOF Data Storage Exception on boot with kernel built
                    with devel/powerpc64-xtoolchain-gcc
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: powerpc
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: kennethsalerno at yahoo.com

11.1-RELEASE kernel built with XCC devel/powerpc64-xtoolchain-gcc (GCC 6.3.1)
fails to boot from qemu-system-ppc64 -m pseries (SLOF fw) with Data Storage
Exception. Crashes just before CPU detection (following FreeBSD version
banner).

The same kernel built without XCC boots as expected.

Please let me know what output or logs would be useful to troubleshoot this
issue. It is not clear to me if this is a SLOF stack issue or compiler issue.
