Description of problem: When I boot installed Fedora 21 on Mac Mini, the whole system freezes, either in gdm, or right after log in. I've found this crash in abrt-cli, I assume it's related to it.

It's interesting that when I boot F21 Workstation Live (RC5), which I installed the system from, I have no problems at all.
So, the system freeze occurs in about 50% of boots. The other half works OK in graphics.
