Yep, x86_64-randconfig (http://kisskb.ellerman.id.au/kisskb/buildresult/9110794/): LZ4 arch/x86/boot/compressed/vmlinux.bin.lz4 /bin/sh: lz4c: command not found Also, several of the blackfin builds started failing due to a compression-related issue, e.g. http://kisskb.ellerman.id.au/kisskb/buildresult/9101322/: UIMAGE arch/blackfin/boot/uImage.lzma Invalid Compression Type - valid names are: none, bzip2, gzip Usage: /usr/local/bin/mkimage -l image -l ==> list image header information /usr/local/bin/mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image -A ==> set architecture to 'arch' -O ==> set operating system to 'os' -T ==> set image type to 'type' -C ==> set compression type 'comp' -a ==> set load address to 'addr' (hex) -e ==> set entry point to 'ep' (hex) -n ==> set image name to 'name' -d ==> use image data from 'datafile' -x ==> set XIP (execute in place) make[2]: *** [arch/blackfin/boot/uImage.lzma] Error 1 May be unrelated, though.
