RHEL 6 shutdown problem


Hi,

Since the time I installed RHEL6 on my Dell XPS laptop, I am facing a strange problem.

After shutting down my machine It will never power off automatically. This machine hangs at line "System Halted.".

While installation machine used to stop at line "Waiting for hardware to initialize". But I found solution on internet to solve that problem by using acpi=off. Now I don't know how to resolve this problem.


Please help!!


Thanks,
Amit

How are you trying to shut down your computer? Do you hit shutdown from the desktop?

Try the
Code:
shutdown now
The
Code:
shutdown -h
doesn't actually poweroff the computer it just brings it to a halt state to where its safe to turn off the computer. I can only imagine that the shutdown menu item in the gnome desktop is using the
Code:
shutdown -h
command.

This potions is also having same output. I think there is something with acpi. I googled and found some threads which suggests solution for this problem. But those suggestions are also not working for me.


Thanks,

So you mentioned before, did you append acpi=off to your boot command?

Sorry for late reply.

Yes, I gave acpi=off option while installing OS.

Now this issue has been resolved after changing acpi=off to acpi=force in /etc/grub.conf. Also added option pci=noacpi in grub.conf.
