on bug 68059
from Thomas DEBESSE
Hi, also get a graphical hang with "[drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed" but without having to suspend or hibernate, to got this bug I just have to boot my system and wait less than 10min before it hangs. The system was still usable by ssh, but the "reboot" never complete. I run 3.2 kernel on Ubuntu Wily with mesa git (I'm using some nightly build packages). I have a radeon R9 390X (Hawaii), lspci says that: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii XT [Radeon R9 290X] [1002:67b0] (rev 80) (prog-if 00 [VGA controller]) dmesg says that: [drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed I join a detailed lspci entry, a complete dmesg log and a screen photo. I remember now that I get the same bug on a radeon HD 7970 (Tahiti) some months ago, lspci line was: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970/8970 OEM / R9 280X] [1002:6798] (prog-if 00 [VGA controller]) The only way to run the radeon R9 390X is to run radeon.dpm=0 (it was needed too for the radeon HD 7970 I had in the past).
