I am > attaching my config file, just in case. Thanks for the report! I'd like to reproduce the issue since I am not sure how this change caused it... I tried to build a kernel with the attached config file, and got the following error. Not sure what I am missing. ---- $ make -j24 ARCH=i386 : LD drivers/built-in.o LINK vmlinux ./.config: line 44: $'\r': command not found Makefile:929: recipe for target 'vmlinux' failed make: *** [vmlinux] Error 127 ---- Do you have steps to reproduce the issue? Or do you see it during boot-time?
