Mac Mini, Yosemite reboot loop (** GPU Hardware VM is disabled)
I have a mid-2011 Mac Mini that has started to reboot spontaneously. I have ruled out hard drive and replaced RAM, but this is still happening. After several of these, the machine gets stuck in a reboot loop, from which it doesn't recover. I managed to get video of it in verbose mode, and the last line is:
** GPU Hardware VM is disabled (multispace: disabled, page table updates with DMA: disabled)
I ran Linc's script, and here is the full output:
Boot Mode: Normal

The machine will run (seemingly) indefinitely in Safe Mode. Anyone have any ideas? This feels like it might be a GPU issue to me, but the fact is it does seem to have started since I upgraded to Yosemite.
Mac mini, OS X Yosemite (10.10.1)
