I suspect this has nothing to do with the shell, or busybox, or
uClibc, and has everything to do with your kernel module causing
a kernel oops, which is crashing your kernel and thus after
calling insmod nothing works since your kernel is now completely

Tried connecting a serial cable and setting up a serial console?
I bet you will see the kernel is oopsing when you load whatever
it is that you are trying to load into kernel space,
