I tried loading an external module (build for ARCH=um type). I am able to load that module only if i've booted UML with following command: ./linux ubda=<raw_file_system_path> If i pass the mem parameter, i.e. ./linux ubda=<raw_file_system_path> mem=512M I am not able to load the module. The error that I am seeing is: overflow in relocation type 11 val a121c3c0 `tun' likely not compiled with -mcmodel=kernel I tried to load the tun.ko. This holds true for any manually built simple hello_world kind of module too (where i added -mcmodel=kernel parameter in Makefile). What can be wrong with "mem=512M" parameter? I change the size of mem to 128K to 1G, but nothing works. It just doesn't like "mem" parameter as bootargs. > > This worked.
