Red Hat Bugzilla – Bug 181446
acpi poweroff and powernow don't work with Asus A8N-VM CSM
Last modified: 2015-01-04 17:25:14 EST
Seems like powernow is not supported for this board and poweroff just results in
the System halted message but stayes alive.

I've just installed FC5 test 3 on my new A8N-E board and have the same problem.
The last message on the screen says it is powering off, but the power down
does not actually happen. I do have Xen installed and it boots the hypervisor
kernel, so that may be related. Also running a dual core athlon which I suppose
might affect things as well.
Strange enough: Booting a FC4 Rescue mode (needed to try something out) writing
poweroff actually switched the computer off... so bug in FC5 kernel due to the
acpi changes I suspect...
Nice keywords there ;) ... poweroff not turning of the computer still present
(and all the same) with latest kernels...
This bug is most likely related to the ACPI problems caused by this motherboard
and/or chipset (nforce 410), here's a link with more details of the MB spec:
My motherboard is an A8N-VM which is almost identical to A8N-VM CSM except with
slower video and some other minor differences.
I've attached the /var/log/messages file that shows the acpi errors when FC is
booted. Hopefully this helps diagnose the problem a little better. Let me know
if I can provide any other info to help fix this bug.

Did you try this pages.
Let me know what you all think.
I am thinking of getting CSM board and would like you all recommendation.
Fixed with latest BIOS from Asus
