Hi. I'm having a similar GPU lockup CP stall on a REDWOOD card. But it doesn't happen at login. With kernels 3.9, 3.10 I can run Xorg, use KDE Kwin effects without any issue; but when I start a game like 0a.d. or Need for Speed Most Wanted under wine, after some time a lockup happens. With kernel 3.11-rc3 lockups occurs while in desktop, little time after login -with or without radeon.dpm set to 1-.
Here are two attachments (the two running a kernel 3.10) of dmesg, one with R600_HYPERZ=0 env var set, and the other not (as suggested on another bug).
Is there anything else I can help?
