I haven't tried it. I'm fairly certain it was a bad kernel build or rpm 
download because it hasn't happened with any kernel before or since; yet it has 
the same transient occurrence even after reinstalling regardless of Btrfs 
compression options. If it's useful, I'll try to reproduce with 
linuxefi/initrdefi and if so, try to reproduce with linux/initrd.
