You need to find out the exact address of this instruction.
I don't have an example handy, but on Internet you can find
the C code of a SIGILL handler which reports the address
of failing instruction and exits.

Then just run

$TARGET-objdump -dr busybox_unstripped

and find in _which function_ it happens.

Run "make networking/ping.s" and generate assembler output,
and find failing instruction in ping.s

Then post collected information to the list.
