    Hello All,

    my second post ;-) I'm still fiddling with the kernel from ""

    I've did a stage-3 gentoo install on a sata drive which works fine, if i use the precompiled kernel. Now I've changed the config a little (ip-tables ...) still using the mentioned kernel sources.

    I've did the following:

    1) linked the kernel-sources to /usr/src/linux
    2) make clean
    3) cat /proc/config.gz | gunzip > .config
    4) make -j4 uImage LOADADDR=0x12000000
    5) copied the uImage to /boot
    6) make modules && make modules_install
    7) reboot with seriell console connected ...... and ....

    the result is:

    UDOO board => run sataboot

    ups ... maybe i have to figure the meaning of

    Please: Give me some hints ;-)
