	Any attempt to write a radioctl variable causes the kernel
	to report an unaligned access. Obviously, there are alignment
	bugs in the radioctl code. Because the kernel is doing a fixup,
	the code still works.

	radioctl -w volume=255
	pid 164 (radioctl): unaligned access: va=0x1200131b4 pc=0x120001e10 ra=0x120001c84 sp=0x1fffff530 op=stq
	volume: 0 -> 255
