On one of my machines, an Ivy Bridge desktop with a Radeon X550 (RV370) graphics card, 3.17-rc1 causes random screen corruption with X running. Eventually X stopped honoring mouse or keyboard clicks, and when I tried to reboot it via an ssh login from another machine, it hanged hard. 3.16 and earlier kernels work perfectly.
After rebooting there was nothing interesting in /var/log/messages, but Xorg.0.log.old showed the following: (EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
