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

Build:

* omap1_defconfig_5912osk_only: implicit declaration of function 'cpu_is_omap15xx'
  - Fixed by Aaro: http://www.spinics.net/lists/linux-omap/msg87523.html

PM:

* 4460pandaes: CORE, L3INIT didn't enter target state
  - Caused by 17b7e7d33530e2bbd3bdc90f4db09b91cfdde2bb
    (ARM: OMAP4: clock/hwmod data: start to remove some IP block control
     "clocks")
  - Fixed by "ARM: OMAP4: PM: fix PM regression introduced by recent clock
    cleanup"
    - http://www.spinics.net/lists/arm-kernel/msg224419.html

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

Build:

* am33xx_only, omap2plus_defconfig_2430sdp_only: omap-{smp,hotplug}.c link errors

Boot tests:

* 3517EVM & CM-T3517: boot hangs with NFS root
  - Likely some Kconfig, board file, and PM issues with EMAC
  - Longstanding bug

Boot warnings:

* 2430sdp & 37xxevm: nasty lock warning due to NFS root
  - Cause unknown
  - Breaks most remaining tests

* 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: pwrdm state mismatch(dsp_pwrdm) 0 != 3
  - need to doublecheck wakeup dependencies
  - (am assuming it's still there; userspace problems prevent the test
     from running, probably due to the lock warning)

* 2430sdp: power domains not entering retention
  - Cause unknown
  - (am assuming it's still there; userspace problems prevent the test
     from running, probably due to the lock warning)

* 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

* 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 reports this does not appear with the same X-loader/bootloader
    on his 4430ES2.3 Panda, so could be ES-level dependent
