Kernel booting problem.

Hi All, I compiled my own kernel image with uclibc cross tool chain for x86 i686 arch. I am using grub as boot loader. these are the following parameters I am giving. kernel /bzImage ro root=/dev/VolGroup00/LogVol00 rhgb quiet init=/sbin/init initrd /initrd.img -----> this is cpio image of filesystem structure with needed modules and lib When I select at grub options to boot the kernel after reading bzImage grub proceeds to initrd and stuck at initrd. There is no output. I searched online and I found other kind of problems. But this is something different. Can anyone give some suggestions. Thanks in advance. -- Regards, Sri.
