Error in booting(DD-WRT) -- need help

Hi all,
I am using DD-WRT-SP1-V24 with Linux-2.6.34.6. When I try to boot the compiled firmware image, it gives the following error:

"Kernel panic - not syncing: No init found. Try passing init= option to kernel"

The corresponding bootlog is shown below.

I am using uboot as bootloader.From this bootlog it can be seen that rootfs is mounted properly also there is no messege related to inital console failure.I cannot get any clue what the problem is.
Please help me out.

Thanks in advance.

A little improvement in the

A little improvement in the status...
Here I am getting some new error message "Failed to execute /sbin/init. Attempting defaults..."

For this I did the following debuging.....

1.Thre is the binary of init exists in target/sbin directory in the following path--->

DD-WRT/src/router/mips-uclibc/target/sbin/init

2.The init binary's architecture matches the hardware.

init: ELF 32-bit MSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), dynamically linked (uses shared libs), not stripped

3. The required library dependencies of the init binary are ...

0x00000001 (NEEDED) Shared library: [libnvram.so]
0x00000001 (NEEDED) Shared library: [libutils.so]
0x00000001 (NEEDED) Shared library: [libc.so.0]
0x00000001 (NEEDED) Shared library: [libgcc_s.so.1]

All are present in the following paths-->

DD-WRT/src/router/mips-uclibc/target/lib/libnvram.so
DD-WRT/src/router/mips-uclibc/target/usr/lib/libutils.so
DD-WRT/src/router/mips-uclibc/target/lib/libc.so.0
DD-WRT/src/router/mips-uclibc/target/lib/libgcc_s.so.1

All the libraries are compiled for desired architecture...

target/lib/libnvram.so: ELF 32-bit MSB shared object, MIPS, MIPS32 rel2 version 1 (SYSV), stripped
target/usr/lib/libutils.so: ELF 32-bit MSB shared object, MIPS, MIPS32 rel2 version 1 (SYSV), not stripped
target/lib/libc.so.0: ELF 32-bit MSB shared object, MIPS, MIPS32 version 1 (SYSV), stripped
targat/lib/libgcc_s.so.1: ELF 32-bit MSB shared object, MIPS, MIPS32 version 1 (SYSV), not stripped

4. Tried to print kernel_execve()'s return value and it is -2, Which indicates that the cause of the problem is "No such file or directory".

Any help will be highly appreciated.

The "Kernel panic - not

The "Kernel panic - not syncing: No init found" problem is solved....the libraries needed by init were not optimized. After proper optimization of the dependencies, init started to boot.

But now I am facing a new problem...execution of startservice is failed. In my distribution startservice is linked to rc(executable) and the rc has execution permission for user,owner and group.
After lot of debugging I found that system() is unable to execute startservice as it cannot find it, though it is present in /sbin/startservice.

The corresponding portion of the bootlog is shown below.
