Hi Andreas--
I took a look at your discussion thread and it seems our circumstances
are a little different but they could be related.
First, if you want more debug info you could try these items (maybe
more) in your kernel config:
CONFIG_OMAP2_DSS_DEBUG=y
CONFIG_OMAP2_DSS_DEBUGFS=y
CONFIG_FB_OMAP2_DEBUG_SUPPORT=y
Second, I'm attaching a the dmesg output that covers a finishing boot ->
display off -> display on cycle. These are the timestamps of interest:
10.94 = the board has booted up and the gnome is starting
196.70 = gnome user is logged in and around here is the last touch
screen tap/input
782.25 = (about 10 minutes later) screen timeout/blank occurs
4102.58 = touch the screen again to wake it up--backlight goes on
but screen is still blank
From what I see in the log it "looks okay to me". In other words,
nothing obviously bad jumps out. So it got me wondering: what if the
context being saved/restored is itself corrupted--is there a way to
determine that? Or, is there a way to prevent the sleeping in the first
place?
Should I move this discussion to the kernel mailing list you cite? I
don't want to spam the Angstrom list if there's a different list that's
better suited.

4) my display (10-inch capacitive touch from Chalkboard Elec) times out
after a while but will not wake up again--even though the backlight remains
on the entire time? this one is especially annoying because the only way I
can recover (that I've figured out so far!) is to reset the BBxm
Maybe I have similar on gumstix overo with kernel 3.8.5 and previous
versions. I wrote some notes in kernel mailing list without helping
response yet [1]. Could you supply some console log error message
when this happens?
