--- Comment #2 from Sasha Levin <sasha.levin at oracle dot com> ---
PR61848 is talking about a "linux kernel boot failure when compiled using
trunk gcc.". In this case, the kernel boots just fine, but it has problem
executing tasks.

I've double checked that for:
svn+ssh://gcc.gnu.org/svn/gcc/trunk@213753

The issue occurs, while for:
svn+ssh://gcc.gnu.org/svn/gcc/trunk@213751

The kernel works fine.
