I made an image on openwrt 12.09, everything is fine.
But later on I added easycwmp-1.1.3, there are some problems.

The boot info without easycwmp-1.1.3:

We can see, if boot without easycwmp-1.1.3,
leds,
Backport,
cfg80211,
PPP,
tun,
ip_tables,
NET,
ehci(usb host),
hub(usb),
nf_conntrack,
xt_time,
mmc,
eth0,
eth1,
cfg80211,
br-lan,
all packages/modules will be inited successfully.

but if boot with easycwmp-1.1.3, initing is stucked at here:
Nov  4 04:11:09 crond[547]: crond: crond (busybox 1.19.4) started, log level 5

The openwrt is 12.09.
Could anyone help to solve it?

Now I try to restore my openwrt system to the state before installing easycwmp.

I deselected easycwmp and deselected its supported libs - libcurl and libmicroxml (other supported libs are shared with other packages and cannot be deselected). then run "make menuconfig clean" "make".

but booting is still stucked at here:

Nov  4 04:11:09 crond[547]: crond: crond (busybox 1.19.4) started, log level 5

Obviously, easycwmp does not directly cause the problem. and our openwrt system cannot be restore, its image size is 64KB larger than once before installing easycwmp.

It should be in the course of installing easycwmp, some unknowed soft module/package was quietly introduced (i.e. busybox function.. just for example). Since I did not save ".config" before installing easycwmp, so I entered menuconfig but cannot find any clue.

How to "make menuconfig" to solve it or any other quick solution?

Per my checking with older ".config", three modules were possibly added:

kmod-lib-crc-itu-t
kmod-lib-crc7
zlib

I wonder if zlib couse that problem?

Solved!

I copied a script 'boot' from Windows 7 OS, coincidentally in the moment of adding eacycwmp package.

Never copy a linux script directly from Windows OS! Though both look like exactly the same.
