Somebody in the thread at some point said:

|         Right now, I use andy-tracking branch, and the version I built
| was 2eb3742db1ecd3d9ffe8f02eaa8def1b2bd2a2c2.
|         I copied arch/arm/configs/gta02-moredrivers-defconfig to
| .config, then I used the build script to build.
|         After the build, I got uImage-GTA02.bin and
| uImage-moredrivers-GTA02_andy-tracking_2eb3742db1ecd3d9.bin. I think
| they are the same. That are the image I used.
|         I changed the runlevel to 3 and tried as I can. The resume
| seemed not work for me. and I got a resume panic log by using debug
| board, as attached file.   Any ideas about what I may do wrong ?

First what's up with your terminal emulator, you need to set it to add
CR to LF or use a more normal one.

Did you have a uSD in the device at this time?

The first two backtraces are not "panics" but warning backtraces about
sequencing of regulator stuffs, to show where the code that needs work
is and how we got there.  They're on my list of stuff to fix, but these
are not fatal errors.

Then there is this:

I'm not running apmd and I don't get any trouble therefore... what is
apmd doing?  Is this because you suspended by apm -s?
