Hi Mike, Can you provide a bit more details about your setup and config ? Are you using GCC or LLVM ? What version of GCC and BINUTILS or what version of LLVM ? What is DEBIAN defconfig ? Does it correspond to one of the standard mainline kernel defconfigs ? If not can you provide it ? Thanks Christophe
