The issues I'm currently looking into is improper mount/detection of the sdcard vfat partition (it mounts just fine in /mnt/media_rw but never seems to be mountable, or accessible from /sdcard), The time either lags or freezes after going into deep sleep (notice this most while charging for the night and waking up to see a 2 hour old time, solved on reboot), Maps works but has the rendering glitch, usually caused by gsf. Also the ramdisk needs to be cleaned and organized. There's unnecessary hardware loads in some of the files and duplicate loads, this makes the bootup logcat harder to debug. It seems that for sdcard mounting we need to not use the external sdcard method but instead duplicate the mount method used by phones with only internal storage. As for the mtdblocks, we can probably either have a slim stable build there which the boot can load after checking for /dev/mmcblk0's presence or use it as swapspace.
Can someone link me to the current repo and device config for the release? I think there's something framework level blocking some of my fix attempts from the ramdisk.
