Going once....

I'm probably going to attempt an upgrade to -CURRENT at the end of this week,
so if anyone is actually interested in debugging this problem with me then
they should contact me ASAP.

I consider this error pretty darn bad because I can't run a debug kernel
anymore. Do we really want to ship 5.2.1-RELEASE with this kind of a bug
lurking in the wings?
