Update:

 

Sleep, shutdown, and brightness control are now working again. I'm not sure why, though. My first idea was that it was rebuilding the kernel extension cache that helped. I reinstalled some kernel extensions for backlight control recently and had to rebuild it.

 

I don't know about the ePSA test... I think I'll just go to the Boot Options menu to avoid it on startup.
