Hi Jane and Matt,

It appears there is a fix for this in libdrm-2.4.24. I've packaged this in a PPA for testing convenience:
https://launchpad.net/~bryce/+archive/cherry

To verify the fix I think you could insert this step in the process:

  3.5. Install libdrm dev from https://launchpad.net/~bryce/+archive/cherry

Since this is an upstream cherrypick from a change in a recently released libdrm version, I feel pretty confident we can just roll this into the distro. However I see there's also a small number of other (possibly important) bugfixes in the new version, so I'm going to investigate if we should just update to the newer package.
