Using kernel repo built from the kernel source project can't be stop during the tests.

I downloaded the repo link with the kernel repo, and the testing class can not able to shut down the kernel.

We will probably be deprecating/removing the build-from-source option, since no one is actually doing this anymore and there isn't any obvious reason why someone would want to.

Building from source probably isn't related to this issue, this sounds like the kernel got stuck in an error state somewhere along the way. Any idea how to reproduce this issue, or if it was even an issue (ie. not a problem with running another node at the same time, etc.)?
