Debian kernels disable x32 support by default for security reasons. You can enable it at boot time via the "syscall.x32=y" kernel parameter. Here is the patch that Debian applies to the upstream kernel sources: https://sources.debian.org/src/linux/6.0.10-1/debian/patches/features/x86/x86-make-x32-syscall-support-conditional.patch/ Cheers, Sven
