As I said, the testcase only works with our hardware, and it's also very large. It's one
small test that's part of a huge test suite. It takes a couple hours just to install the
damn thing.

We want to produce a simpler test case that demonstrates the problem in an
easy-to-understand manner, but we don't have time to do that now.
