You know, thanks to Intel’s little ‘design flaw’ in its CPUs and all of that buzz going on, we’re forced to patch around a little. This time, the linux kernel bails out

I mean, it’s a dead simple solution in the end:

chmod +x /usr/src/linux/tools/objtool/sync-check.sh

But where does the problem come from? Digging around I could see the problem at first at 4.14.10. As we’re working quite a lot with ‘patch’ in general and patch does a lot of stuff on git, it’s most likely the one to blame here.
