Hi,
Sometimes my machine hangs in userspace area like this :-
VFS: Mounted root (ext3 filesystem).
Freeing init memory: 124K
INIT:
<<HANGS>>
OR
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.
Is this a deadlock.
Thank you,
Jaswinder Singh.

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.
