--- 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.
