We had recently seen a kernel panic when accidently programming QEMU in an inappropriate way (in short, accessing RD registers before setting the RD base address. See patch #1 for details). And it looks like we're missing some basic checking when handling userspace register access. I've only tested it with QEMU. It'd be appreciated if others can test it with other user tools.
