Reg Linux-2.6.27 hang

Hi ,

we are porting linux 2.6.27 on imx27 based platform. we did all the platform dependent changes .

With this linux is booting till a point and stopping there ..

stopping at

(VFS) Mounting file system

Freeing init memory

While debugging through printk we could go till

rest_init() -> kernel _init() -> init_post() --->

Going for opening initial console . .... using sys_open() .... After that no prints .......

Can any body help us to go forward ?

Thanks in advance ,

Prabha
