Thanks Raimund, that's quite interesting.  It is possible that there are
two different freeze bugs, and that downgrading libdrm fixed the more
severe one but the second one still occurs.

Would you be willing to do a bit more testing to verify if this
hypothesis is correct?

a.  Test with the downgraded libdrm packages installed until the freeze occurs.  With the system in the frozen state, ssh into the box and collect the following:
  * dmesg > dmesg.log
  * /sys/kernel/debug/dri/0/i915_error_state

b.  Now upgrade to the stock libdrm where the freeze occurs every time, and reproduce the freeze.  With it frozen, collect the same data:
  * dmesg > dmesg.log
  * /sys/kernel/debug/dri/0/i915_error_state

Attach all four to this bug report.  I'll review and compare to see if
it is indeed the same bug in both cases, or if actually it's separate
bugs.  If it is separate bugs as I suspect, I can revert the libdrm
patch to at least get that one fixed, and then we can turn focus to the
lesser freeze bug.
