            Bug ID: 90926
           Summary: Unusable GPU
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: artivision3 at gmail.com

Laptop with A6-6310 CPU and R5-M230 dedicated GPU. When using DRI_PRIME=1 the
DGPU hangs in "power level 4" at 850mhz. It doesn't hang in "power level 0" at
300mhz. Disable DPM doesn't solve the problem. Disable
Dynamic_Frequency_Scaling and start at 850mhz doesn't solve the problem. Kernel
version, DRI version, Mesa version "Oibaf PPA or not", composition level (GL,
XRender, or not), Apps 32-64bit, they don't make a difference. Everything hangs
and so i cannot take terminal output from the almost all Apps. Wine hangs
alone, but the terminal doesn't show any errors and then i have to close the
terminal to kill Wine window. PCSX2 shows:
