Comment 5 for bug 1389675

Paul B, I've updated the wiki to clarify which architecture to test, and what the installation command means. As you are using a 64-bit OS, you would want to follow the amd64 instructions.

As well, there isn't a high likelihood of making your install unbootable. If the kernel doesn't work for whatever reason, one may simply boot into the default kernel and follow the support instructions to remove the mainline kernel.
