Thanks, that makes it quicker to try out. I'm now using your config to do more testing. I still don't see it with a normal build though. I do see that setting the timestamp of syscall.tbl to a future date does result in always rebuilding everything, but I don't think that is what you are seeing, since that also produces a warning from make: arnd@studio:~/arm-soc/build/bisect$ touch -t 202501010000 arch/x86/entry/syscalls/syscall_64.tbl arnd@studio:~/arm-soc/build/bisect$ make ARCH=x86 CROSS_COMPILE=x86_64-linux- make[2]: Warning: File 'arch/x86/entry/syscalls/syscall_64.tbl' has modification time 14483017 s in the future SYSHDR arch/x86/include/generated/uapi/asm/unistd_64.h SYSHDR arch/x86/include/generated/uapi/asm/unistd_x32.h SYSHDR arch/x86/include/generated/asm/unistd_64_x32.h SYSTBL arch/x86/include/generated/asm/syscalls_64.h make[2]: warning: Clock skew detected.
