--- Comment #1 from Sam James <sjames at gcc dot gnu.org> --- Please include the full output from a kernel panic (so we can see the backtrace). We will also need you to do the following: a) bisect GCC; b) obtain a build-tree built before and after the bad commit (then can bisect by objects, but I can explain how to do that once you have it)
