Priority: medium Bug ID: 66880 Assignee: dri-devel@lists.freedesktop.org Summary: R600_DEBUG=sb hangs system after playing xonotic, spring Severity: normal Classification: Unclassified OS: Linux (All) Reporter: pheldens@ziggo.nl Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

linux 3.10.* and before R600_DEBUG=sb radeon 4670

crashes in xonotic and spring after indeterminate time, colours the screen with garbage, does not crash when R600_DEBUG is unset.

all I caught so far is a kernel oops output
