   I have these problems also, and adding "rw" to append-GTA02 didn't
solve it. Full content of my /boot/append-GTA02 is this: "console=tty0
loglevel=8 rootdelay=1 rw" (brainless copy-paste of everything related
from Qi wiki page[1]).
   Problem is, I can't even tell for sure if Neo (Qi actually) boots
from uSD or NAND. Hurting my eyes on running on-screen log I saw
something like "Waiting for 1sec before rootfs", which suggests that
it's Qi taking appeng-GTA02 into consideration. Still I have multiple
"read-only filesystem" tar warnings.
   Every power-up after battery out+in gives Neo several seconds to
boot up -- detailed logs on screen -- then it just switches off. Next
boots freezes like described by other people in this thread. First
"successful" boot freezed on these lines in on-screen log:
asoc: WM8753 HiFi <-> s3c24xx-2c mapping ok
asoc: WM8753 Voice <-> Bluetooth mappgin ok
Only GTA01 hardware supported by ASoc driver
   Next "successful" boot ended up with previous lines plus this
(<...> means long message):
mount: special device /dev/mmcblk0p1 does not exist
ALSA: <...>
<...> load_state:1327: No soundcard found...
usb0: link is not ready
done.
   And it freezed again. uSD card must be good, because I can
read-write it through notebook card reader and if I go to NAND menu
and modify boot command line to load from uSD, it works just fine.
Behaviour is unstable: I could boot (from NAND!) *once* while trying
to boot from uSD/Qi , and it's the same with 2008.12 release as well
as with 04.01.2009 testing. I also boot with SIM card inserted so weak
uSD reader contacts shouldn't be an issue.
   Should I return to u-boot technique for starting up Neo? I wanted
to give Qi a try for it is a "modern" way of doing things.
