Priority: medium Bug ID: 76046 Assignee: dri-devel@lists.freedesktop.org Summary: [r600g][RV635][LLVM shader] Chrome aborts GPU acceleration Severity: normal Classification: Unclassified OS: All Reporter: shawn.starr@rogers.com Hardware: Other Status: NEW Version: unspecified Component: Drivers/Gallium/r600 Product: Mesa

Forcing GPU accelration on r600g w/ (now using LLVM R600_LLVM=1 default it seems) causes an assert to be thrown.
