Currently our compression options vary from those used in upstream kernel. As of 6.8-rc2 upstream uses (ignoring force/rm input file etc): - gzip -9 - xz --check=crc32 --lzma2=dict=1MiB Note: some older kernels lacked crc32 and/or used 2MiB - zstd -T0 (aka -3) With the higher dictionary size (xz) and compression size (20+ zstd) more memory is required for decompression. Which may be a problem if the kernel itself is responsible for the decompression (instead of kmod), since it uses a smaller/limited ram amount. Reduce the numbers of be compatible with upstream.
