Priority: medium Bug ID: 63748 Assignee: dri-devel@lists.freedesktop.org Summary: GPU Lockup playing urban terror Severity: major Classification: Unclassified OS: Linux (All) Reporter: dinolib@libero.it Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI

Playing UrT just few minutes, bring to CPU lockup rescued in some seconds with a softreset. Sometimes the system can't recover from this state.

Before Mesa 9 (and relative dri drivers) update never happened.

01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880M [Mobility Radeon HD 4200 Series]
