[Bug 225182] devel/powerpc64-xtoolchain-gcc: SLOF Data Storage Exception on boot with kernel built with devel/powerpc64-xtoolchain-gcc

--- Comment #27 from Kenneth Salerno <kennethsalerno at yahoo.com> ---
This issue is fixed in 11.2-BETA2 (I was able to boot a kernel built with
lang/gcc7 cross-compiled amd64->ppc64, only after installing the new boot
loader for 11.2). You may close this ticket.
