    | hi randy!

    | thank you very much for your help.
    |
    | it is indeed the % (mod) operator that generates the
    | unresolved symbol. it is also true with the /
    | (division) operator.
    |
    | is there any patch on this for
    | 2.4.18-sh? or how will i do away with this problem
    | aside from commenting it out from the code?

    Sorry, I don't track sh changes. However, I do see in 2.4.26
    that arch/sh/lib/udivdi3.c contains a __udivdi3() function,
    so perhaps you could manage to use it or implement something
    similar to it.

    Or perhaps you could use a different kernel version.

    | btw, the previous unresolved symbol problems were
    | already solved. i just didn't copy the depmod
    | generated files in the running machine, that was why
    | those occured.

    Good.
