If https://gitlab.com/Linaro/lkft/mirrors/stable/linux-stable-rc/-/jobs/1428532107 is the logfile for this problem, than i see the following in the log: make --silent --keep-going --jobs=8 O=/home/tuxbuild/.cache/tuxmake/builds/current ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- 'CC=sccache s390x-linux-gnu-gcc' 'HOSTCC=sccache gcc' /bin/sh: 1: /builds/linux/arch/s390/kernel/vdso64/gen_vdso_offsets.sh: Permission denied However, in the patch this script is 755, and other architecture are using this for a while now - can you check what the permission are when you're trying to build the kernel? Thanks Sven
