but probably something (important) is missing in the patch?
Anyway - the BUG is the same, but for the first call in the NFSroot I get
the correct error from the linker (see log):
/root/bin/ls: error while loading shared libraries: librt.so.1: cannot

Second call crashes again, same BUG.

BTW - my kernel is allmost an "allmodconfig", "allyesconfig" kernel, as
the config is based on the Debian one, with quite some experimental stuff

Thanks
