Can´t build kernel 4.14.15

English Install/Boot/Login
#1

I hope this is the right subforum to ask for kernel stuff…

I try to build the latest kernel from the stable kernel repo that is 4.14.15-5.
But it always fails, I always get a segfault in objtool at some point.

Some people suggest RETPOLINE to be the bad guy that segfaults objtool.
Thus, I disabled RETPOLINE, but did not help either…

Then I tried to use *CONFIG_UNWINDER_FRAME_POINTER=y *and disable RETPOLINE the same time, did not help again.

I´m a bit displaired now, any suggestions?
Though, I use march=bdver2 to optimize for AMD FX. Could this cause trouble?

**System used:
Leap 42.3
GCC7 gcc 7.3.0
**AMD FX CPU with march=bdver2

#2

I think I might only be able to build 4.14.15-5 with

**CONFIG_UNWINDER_FRAME_POINTER=y

CONFIG_RETPOLINE is not set

But, I´d like to have retpoline activated…
