[Bug 64320] New: WebGL support in Chrome causes GPU lockup

https://bugs.freedesktop.org/show_bug.cgi?id=64320

Priority: medium Bug ID: 64320 Assignee: dri-devel@lists.freedesktop.org Summary: WebGL support in Chrome causes GPU lockup Severity: normal Classification: Unclassified OS: Linux (All) Reporter: marvin24@gmx.de Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

googles chrome browser causes gpu lockup on my RS880 while showing maps.google.com and enabling WebGL renderer. For this to work, you need to manually override gpu blacklist with "--enable-webgl --ignore-gpu-blacklist" on the command prompt. Check with about:gpu that hw accel is enabled.

Mesa/LLVM/drm/ddx is from today (May 7th) and kernel is 3.9.

dmesg shows:
