Unfortunately the LTS version of Ubuntu (trusty) was updated to 2.4.60 several days ago without this fix. I repackaged libdrm 2.4.60 with only the bug fix above and confirm the patch above fixes the observed behavior in freedesktop bug# 89842/ debian bug# 789759. I pushed the repackage to Launchpad PPA @ ppa:phurley/libdrm Hopefully the Debian maintainer grabs this fix and updates the official distribution version soon.
