Fair point.  I've actually been working on the GTA02 resume failures,
but no breakthroughs at all.

I originally observed the issue on "stable".

I observed similar symptoms, and finally got back to a state where I
could work on this more carefully yesterday, in fact.

I could not replicate the problem yesterday at all.  Last night I got
both the old GTA01 and the new GTA02 running the same rootfs image, both
from SD card, with the same kernel (different defconfigs, of course).  I
left both unplugged (battery-only), with SIM cards, side-by-side overnight.

Both were silent and apparently suspended some 8 hours later.  I sent
both an SMS -- and both awoke.

Curiously, the battery on the GTA01 was still in very fine shape - the
GTA02 was almost completely flat.  I was not expecting that, I need to
go over the logs to see if the GTA02 spent the night resuming and
suspending, or if suspend left something turned on that it shouldn't
have.  Since it's the same kernel and rootfs, I suspect perhaps it's the

The next step is to get the debug board attached to the GTA02 - but one
of the big delays in working on this further was that I seemed to have
encountered a connector problem with the debug board when I tried to
move it from the GTA01 to the GTA02. :(  Hopefully that's just my clumsy
fingers and not a permanent problem.

:)  They'll toss me off the list long before you'll be evicted!  :-D
I guess I'm interested to know what Linux version you're running - did I
understand that you are seeing this with 2.6.25?
