Revision 761bfb999868c413aabed8caa345694836ec6f11 authored by Alex Deucher on 06 August 2013, 17:34:00 UTC, committed by Alex Deucher on 07 August 2013, 21:37:19 UTC
The rlc is required for dpm to work properly, so if
the rlc ucode is missing, don't enable dpm.  Enabling
dpm without the rlc enabled can result in hangs.
