Andy,
Thismorning the A5 I have acts strange with shutting itself down
randomly so I made a note on our task list to examine this question
later.

Is it shutting itself down when running from battery?
Try running from USB and see whether you have the same problem there.
Whenever you run into what you believe is a hardware problem, can you
add that incident to
http://wiki.openmoko.org/wiki/Prototypes
Erin had a similar shutdown problem (see #15 on the wiki page), Matt
is currently looking into it.
Can you get in touch with Matt/Erin to find out whether you have the
same problem or a different one?

Somebody in the thread at some point said:
I've a comment about having SD turned off during suspend mode, how
does
this affect the users running OpenMoko from the SD-card rather than
NAND?
I think this answer right now is "Dunno".
As it stands we don't actually make that decision to take power from
the
SD Card, the MCI stack in Linux is sending our Glamo MMC driver a
request to pull power on suspend. Linux also goes through the steps
itself to unregister the block device for the card and recognize it
fresh on resume.
Before suspend, quite early there is a "sync" action to flush stuff
but
I didn't see any umount type action, maybe it just happens quietly
because I didn't see any noise about FS trashing. But it is VFAT on
the
cards rather than anything more complicated.
It does re-recognize the card I saw before on resume and recreate the
block device for the card and partitions. The question is if the
mount
action is done and what happened to apps that had handles open on the
thing... esp when the filesystem is the root filesystem.
