Bug 1317680

Description of problem:

I installed F24 on a machine that had 'secure boot' enable (unbeknownst to me).  I went to load a custom kernel to debug the bluetooth driver and grub2 barfed with a 'double free' after loading the kernel.

That was all that was on the screen: 'double free <address>'

A couple of 'echo' statements inside grub2.cfg led me to realize it was failing on loading the kernel.

It wasn't until I compiled my own grub2 rpm, that things went south on next boot, when the MOK manager popped up complaining about invalid key.

I then realized secure boot was enabled, and disabling it resolved my problem.


What am I reporting in this bugzilla?  The double free and/or the lack of a better error message on the failed kernel attempt.  I was hoping a better error message would have saved me a few hours of kernel compiling and grub2 compiling.
