Why simply not disassembling the kernel and looking at what is at
0xc002d3c8 and looking at the values of the registers? It is entirely
possible that the RTnet IP stack requires unaligned accesses (the
vanilla kernel does it, notably for handling of IP options), and as you
may know it, unaligned accesses may require software emulation on some
platforms. However, I am not sure you would get an exception #0 in that
case. Your post does not even tell us on what platform you get this
issue, though I suspect this is ARM.
