Sometimes my machine hangs in userspace area like this :-

VFS: Mounted root (ext3 filesystem).
Freeing init memory: 124K
INIT: version 2.85 booting
<<RUNNING SMOOTHLY>>

How can I debug this hang, what are the cases.

When it hangs, try to capture the list of processes using Alt+SysRq+T. You need to have CONFIG_MAGIC_SYSRQ enabled in the kernel.
