Hi,
I am trying to boot my android tablet from SD Card. I used the original
kernel and system image and
put then on SD card. I only changed the init files to reflect SD boot.
The kernel boots fine but android GUI appears to be stuck at boot
animation. I find some errors on the
console log and I wondering what could be the issue.
Here are the relevant logs:

<----------------------- (SD card seems to be initialized here..)
[ 3.570000] mmcblk0: p1 p2 p3 p4 < p5 p6 >
[ 3.600000] EXT4-fs (mmcblk0p2): barriers disabled
[ 3.600000] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data

As you can see some mounts and writes failed. Mostly suspect this to be the
issue to SD initializing after
the init has started.
I have put this on top of init.rc:
on fs
mount ext4 /dev/block/mmcblk0p2 /system ro wait noatime nodev barrier=0
wait /dev/block/mmcblk0p5
mount ext4 /dev/block/mmcblk0p5 /data wait noatime nosuid nodev
barrier=0
setupfs /dev/block/mmcblk0p5
umount /data
exec /system/bin/logwrapper /system/bin/e2fsck -y
/dev/block/mmcblk0p5
exec /system/bin/busybox mount -t ext4 -o
noatime,nosuid,nodev,barrier=0,journal_checksum,noauto_da_alloc
/dev/block/mmcblk0p5 /data
mount ext4 /dev/block/mmcblk0p3 /cache wait noatime nosuid nodev
barrier=0
setupfs /dev/block/mmcblk0p3
umount /cache
exec /system/bin/logwrapper /system/bin/e2fsck -y
/dev/block/mmcblk0p3
exec /system/bin/busybox mount -t ext4 -o
noatime,nosuid,nodev,barrier=0,journal_checksum,noauto_da_alloc
/dev/block/mmcblk0p3 /cache
But still the init proceeded. Is there any way to delay the init?
Any ideas on what could be the issue and how to solve it?
Thanks
