--- Comment #29 from Mark Janes <mark.a.janes at intel.com> ---
I am seeing "*ERROR* timed out waiting for Punit" on production Baytrail
systems, and it seems related to an eventual system hang.

Environment:
 - Debian sid
 - 3.18 kernel
 - Lenovo 500s
 - mesa, drm, piglit, and waffle from master

Running the piglit "quick" test suite will generate hundreds of these messages.

The machine hangs after one of these messages, every day or so.

Two separate systems display the same behavior.

Systems are available in JF1 if needed to reproduce the message.
