I think I might have found it. Although I have selected in the kernel "menuconfig" to compress the initramfs using gzip and deselected all other decompression forms. a simple "file initramfs-xxx" told me that it was "XZ compressed data", so now I am rebuilding the kernel with all decompression algorithms built in. I will (hope) soon post the results. Thanks, Francisco
