>Description:

I had my kernel stack corrupted during the config process. I'm not sure
whether the second processor had launched yet. The stack would get corrupted
and the framepointer would get wiped. The ultimate fix was to remove the usage
of a 2KB automatic variable.

It seems to me that there should have been some kind of warning about this.
