Here are some basic OMAP boot and power management test results for 
v3.6-rc6:

   http://www.pwsan.com/omap/testlogs/test_v3.6-rc6/20120918101040/

Some observations:

Boot 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

I'll be able to put some human resources on investigating this
in a couple of weeks hopefully. Currently, it does not affect all
boards (using the same boot loader) and does not look that it interferes
with any functionality later in the boot or runtime.

* 3517EVM & CM-T3517: boot hangs               
  - Probably due to the use of NFS root; there are likely some Kconfig,
    board file, and PM issues with EMAC

Have you tried the nohlt boot parameter?
It looks like the wfi is killing those SoCs once you use EMAC.

PM tests:

* 37xx EVM: CORE not entering dynamic off-idle
  - Cause unknown; dynamic retention-idle seems to work; system suspend to 
    off works

* 3730 Beagle XM: does not serial wake from off-idle suspend when console
  UART doesn't clock gate ("debug ignore_loglevel")
  - Not shown in the current test logs; cause unknown

* 4430ES2 Panda: UART corruption during long transmit buffers
  - Presumably due to either a missing hardware workaround or a bug in
    the OMAP serial driver

Other:

* RCU stall messages appear if boards are booted into a minimal userspace
  and left to sit for a few minutes
  - Fixed by http://marc.info/?l=linux-arm-kernel&m=134835120600590&w=2


Changes from v3.6-rc6 (test 20120918101040):

- Added comments about RCU stalls, appearing since at least v3.6-rc3

- Updated CM-T3517 "USB OTG" (really IPSS) comment
