In source-packet there's some specific kernel configuration, which will not work on most boards. I'm talking about correct memory-detecting for Edimax (or something like that) boards which can be disabled by commenting 'CONFIG_NINO_EDIMAXMEM' in '.config' or in 'make menuconfig' uncheck '8M Tiny selection ---> Add "Edimax" select_at_boot of RAM (8M)'
