--- Comment #13 from Forest Bond <forest at alittletooquiet.net> ---
Sorry about that.  I guess I re-imaged the machine and forgot to re-install the
drm-intel-nightly kernel.

With kms enabled, intel_reg_dumper failed with the following error:

  Couldn't map MMIO region: Resource temporarily unavailable

dmesg for this case is attached.

With kms disabled, intel_reg_dumper succeeded but complained as follows:

  Couldn't find path to dri/debugfs entry

Dump output is attached.

Thanks,
Forest
