Hi,
I turned on pm_debug, dumped all related registers for both systems
and compared them (as attached below). Most registers have quite the
same contents, while some like CORE_MOD.CM_ICLKEN1 and
CORE_MOD.CM_ICLKEN1 there is 1-bit difference (looks like the newer
clock has one UART clock on while sleeping..?)
What is confusing to me is CORE_MOD.PM_PWSTST (the working system has
0x00080010 while the newer system has 0x00080030). Does it mean their
last power states are different?
Can any one take a look the dmesg and offer some suggestions? Thanks.

Quoting xl6@xxxxxxxx:
By 'deeper-sleep state', you mean the full retention mode? I am sure
that pm24xx.c:omap2_enter_full_retention() is called and the
assembly code in sleep24xx.S is executed, by printing some debug info.
Thanks.

It sounds like something is blocking the deeper idle states.
The way to debug is to see what clocks and domains are on
before entering idle.
Maybe do a register dump on a working system and compare that
to the current system?
