Failing tests: fixed by posted patches
--------------------------------------

Build:

* am33xx_only, omap2plus_defconfig_2430sdp_only: omap-{smp,hotplug}.c link errors
  - Discussion & RFC patch: http://www.spinics.net/lists/arm-kernel/msg230017.html
  - Still needs revision of the patch


Failing tests: needing investigation
------------------------------------

Boot tests:

* 3517EVM & CM-T3517: boot hangs with NFS root
  - Likely some Kconfig, board file, and PM issues with EMAC
  - Longstanding bug
  - Not currently part of the automated test suite

Boot warnings:

* CM-T3517: L3 in-band error with IPSS during boot
  - Cause unknown but see http://marc.info/?l=linux-omap&m=134833869730129&w=2
  - Longstanding issue; does not occur on the 3517EVM

PM tests:

* 2430sdp: power domains not entering retention
  - Cause unknown

* 4430es2panda, 4460pandaes: pwrdm state mismatch on CAM, DSS, ABE

* 4460pandaes: pwrdm state mismatch on IVAHD, TESLA 

* 4430es2panda: CORE, TESLA, IVAHD, L3INIT didn't enter target state
  - Probably due to lack of reset code for M3, DSP, SL2IF, FSUSB
    per discussion with Tero Kristo
  - Likely dependent on the bootloader version
    - fails with 2012.07-00136-g755de79
  - http://marc.info/?l=linux-arm-kernel&m=136432340618226&w=2

* 4460pandaes: chip not entering retention in dynamic idle
  - Presumably 4430es2panda also fails this
  - Suspend-to-RAM enters full chip retention

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
  UART doesn't clock-gate ("debug ignore_loglevel")
  - Cause unknown
  - Not yet part of the automated test suite
  - Re-tested at v3.7; still failing:
    http://www.pwsan.com/omap/transcripts/20121211-3730beaglexm-3.7-pm-offmode-fail-debug.txt

Other:

* 4430es2panda: omap_hwmod: l3_instr: _wait_target_disable failed
  - Unknown cause; could be due to the lack of hierarchical enable/disable
    in hwmod code
  - Jon Hunter and Santosh Shilimkar report this does not appear with
    the same X-loader/bootloader on his 4430ES2.3 Panda, so could be
    ES-level dependent

16MiB of the reserved memory increase is probably due to CMA.
