slow boot

[sandro76]

I have a system whit a PXA300 (arm), 512 Mb nand flash JFFS2 and a debian distro.
It have a very slow boot.
At start it executes in rcS.d the attachment script.
I have insert in the script some echo to see where is the problem:

at line 288
...
#
# Remount root to final mode (rw or ro).
#
# See the comments above at the previous "mount -o remount"
# for an explanation why we try this twice.
#
echo 1
if ! mount -n -o remount,$rootopts,$rootmode $fstabroot / 2>/dev/null
then
echo 2
mount -n -o remount,$rootopts,$rootmode /
fi

#
# We only create/modify /etc/mtab if the location where it is
# stored is writable. If /etc/mtab is a symlink into /proc/
# then it is not writable.
#
echo 3
init_mtab=no

...

when I start the system, the messagges in this section is:
1
(wait for long time, like 5 minutes)
3

the only instruction that it executes is
if ! mount -n -o remount,$rootopts,$rootmode $fstabroot / 2>/dev/null.

can you help me to speed up the boot?

It seems to hang when trying to mount a drive. To see the full command that's causing the hang after your "echo 1" line add the following:

echo "Trying: mount -n -o remount,$rootopts,$rootmode $fstabroot"

What is the output from that?

Trying: mount -n -o remount,defaults,rw /dev/root

I read that it's depends to jffs2 file system. This fs it's particularly slow to the boot for large memory because it must check all inodes.
in fact I try to reduce the root partition and the boot it's more fast.
