I assume this is the decompressor, as arch/mips had similar problems. The possible fixes are: - disable lz4 compressed kernels on xtensa - change lz4 to not perform any division - change the xtensa decompressor to include the divsi3 helper code from the main kernel, see fbf3bce45821 ("MIPS: boot/compressed/: add __ashldi3 to target for ZSTD compression") Arnd
