Ok, thanks for enlightening me. I had things confused. So this is a kernel bug list? I thought it is X-related.
https://bugs.freedesktop.org covers lots of projects including the drm kernel drivers. The product and component fields target different parts of the stack. In this case Product = DRI and Component = DRM/Radeon is the radeon kernel driver. Product = Mesa and Component = Drivers/Gallium/r600 would be the mesa driver.
