So while funny, I doubt this is actually a bug. It's a feature, as
pointed out by Clemens Ladisch in that thread.

It's simply sysrq-c: "perform a system crash by a NULL pointer dereference".

Now, I'm perfectly willing to consider that feature to be a
mis-feature, and that this should be considered a bug to be fixed. But
it is not a regression.

Keeping it on the regression list just because it is amusing is
understandable, though ;)
