can you tell me which commit is last good ?
yes there are interaction between kernel and compiler
sometimes kernel code has wrong expectation of gcc and when it gets
fixed in gcc things dont work so in such cases kernel is fixed in some
case kernel may expose real gcc bug too. Cant tell much unless its narrowed down

in some case
