This bug probably would never happen on baremetal unless it was running on broken hardware. BUT!!! With more and more systems going to a virtual environment, having a bug or some other anomaly can trigger the error that this patch prevents. The patch will also trigger a print in the case of running on a buggy virtual machine, which would help out the developers of that virtual machine to fix their code.
