Read-only filesystem.  Once you've booted and see the GSM error in Zhone,
open a terminal and try "touch test" - you'll get an error noting that the
rootfs is read-only.  Qi mounts rootfs read-only at the start - I believe
/etc/init.d/checkroot.sh is where it's supposed to be remounted read/write.

Many things will be 'broken' in this state, like you cannot SSH into it
because dropbear doesn't start properly when it can't write, and just about
everything with frameworkd is broken.

Presuming this is the case (I'm betting;) try 

mount -o remount,rw /
/etc/init.d/frameworkd restart

stop Zhone, restart it, and it should be able to activate GSM...


I've not worked through the logic in /etc/init.d/checkroot.sh or anything
yet to see where this is failing, but putting the remount command at the
top of that script will restore your FR to usefulness, remounting / rw
fairly early in the boot process.  (checkroot.sh is supposed to check the
rootfs for errors /if/ it's ext2/3, and remount r/w afterwards, but doesn't
seem to remount root if it's booted from jffs2 in NAND.  As I said I've not
followed the logic of the script yet but am guessing that if it's not
ext2/3 it never reaches the remount,rw statement there.)
