I am on 3.12.7 and the R600_DEBUG=nohyperz seems to work fine for me. Without it, it crashes after just couple of minutes (machine rebooting automatically). I have a HD6950. So thank you for the tip.
Are you seeing this problem with HyperZ since the introduction of dpm or is it something new (a regression)? Have you tried a 3.13-rcX kernel to see if this is still happening?
