Don't know if this is your case but is /mnt the ISO file? It would be read-only. Run mount /mnt and ensure kernel is building on a R/W filesystem.

Subject: Problem in building iso image
Date: Wed, Aug 28, 2019 12:45

I try to build an iso image from release 3.5 branch and get following
error. What's wrong?

bash-4.4# make kernel
make -C kernel/linux-4.19.61 mrproper
make[1]: Entering directory '/mnt/kernel/linux-4.19.61'
make[2]: *** Documentation/Kbuild: Is a directory.  Stop.
make[1]: *** [Makefile:1316: _clean_Documentation] Error 2
make[1]: Leaving directory '/mnt/kernel/linux-4.19.61'
make: *** [Makefile:98: kernel/linux-4.19.61/arch/x86/boot/bzImage] Error 2

PS. Is it correct that master points on Crux 3.4 release?
