removing module-common.lds from LDFLAGS_MODULE, my machine boots fine
and without any error messages:

--- a/Makefile
+++ b/Makefile

+LDFLAGS_MODULE  =

i hope someone with more insights in these parts of the kernel can have
a closer look into this issue.

thanks, tim

disturbs us. When we listen to it, we find it fascinating.
