Kernel Blues?

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 *– * AR /usr/src/linux-4.14.12/tools/objtool/libsubcmd.a * CC /usr/src/linux-4.14.12/tools/objtool/libstring.o * CC /usr/src/linux-4.14.12/tools/objtool/str_error_r.o * LD /usr/src/linux-4.14.12/tools/objtool/objtool-in.o *make[2]: execvp: ./sync-check.sh: Permission denied *make[2]: *** [Makefile:49: /usr/src/linux-4.14.12/tools/objtool/objtool] Error 127 *make[1]: *** […]

The question is ‘make boot fast’.” – those are the words of two Intel developers rumbling the Linux scene: Arjan van de Ven and Auke Kok. Their idea is a quite uncommon attempt, disregarding the fact that Linus Torvalds dislikes it: They want to boot a whole system […]
