Description Francesco Tapparo 2011-07-02 17:47:47 UTC
Description of problem:
if I type "halt -p" or "poweroff" the pc shutds down but the monitor remain on and I see the classical blue page with the fedora logo in the middle. 

Version-Release number of selected component (if applicable):


How reproducible:
This does not happen in every fedora systems: I've another pc, with another intel graphic card, and the other pc works great. 

Steps to Reproduce:
1. type "halt -p" or "poweroff" as normal logged user
2. wait some seconds
3. you hear the hard disk stopping but the screen remains on (I waited 5 minutes)

I can post additional info on request.

Does "sync && poweroff -f" work any better?
What is the kernel version? Do you use Fedora kernels, or do you build your own?

Comment 2 Francesco Tapparo 2011-07-03 08:11:55 UTC
interestingly, "sync && poweroff -f" does not work any better: the monitor  still remains on. I use official fedora kernels, my current kernel is:

Linux mizar 2.6.38.8-32.fc15.i686.PAE #1 SMP Mon Jun 13 19:55:27 UTC 2011 i686 i686 i386 GNU/Linux

Comment 3 Francesco Tapparo 2011-07-03 08:42:50 UTC
Another information: I tried booting in the fedora 15 and fedora 14 dvd, went to the text console and typed "halt -p". The bug appeared in those versions too.

Suspension correctly work (tried in my current fedora 15 system).

Comment 4 Michal Schmidt 2011-07-03 21:42:07 UTC
Then it's not systemd. Reassigning to kernel.

Boot with the "rhgb quiet" parameters removed from the kernel command line. Try to poweroff again. What are the last lines written on the screen?

The problem must be hardware-specific, so please attach the outputs of "dmesg" and "lspci -nnvvv".

Comment 5 Francesco Tapparo 2011-07-06 05:34:10 UTC
I started the pc after having removed rhgb quiet, then executed "poweroff".
The last lines are:

ACPI: preparing to enter system sleep state S5
disabling non boot BPU
power down


some lines before them I've seen some suspect logs:
ext4-fs: (dm-0): remounted opts:(null)
disabling swaps
detaching loop devices
detaching dm devices 
not all dm devices detached 1 left
detaching dm devices 
not all dm devices detached 1 left

and after that the system renounced to unmount a unspecified dm device

Comment 8 Francesco Tapparo 2011-07-06 05:40:45 UTC
clarification: it was "disabling non boot CPU", not "disabling non boot BPU"

Looks similar to this report from Carsten Emde:

Is this still happening with the 2.6.40.x kernel updates in F15?

> Is this still happening with the 2.6.40.x kernel updates in F15?

Unfortunately yes: it still happens in F15 with the current kernel:

[cesco@mizar ~]$ uname -a
Linux mizar 2.6.40.6-0.fc15.i686.PAE #1 SMP Tue Oct 4 00:44:38 UTC 2011 i686 i686 i386 GNU/Linux

Comment 13 Josh Boyer 2012-06-06 15:44:59 UTC
Still happening with 2.6.43/3.3?  (Apologies for the repeated questions)

Comment 14 Josh Boyer 2012-07-11 17:51:08 UTC
Fedora 15 has reached it's end of life as of June 26, 2012.  As a result, we will not be fixing any remaining bugs found in Fedora 15.

In the event that you have upgraded to a newer release and the bug you reported is still present, please reopen the bug and set the version field to the newest release you have encountered the issue with.  Before doing so, please ensure you are testing the latest kernel update in that release and attach any new and relevant information you may have gathered.

Thank you for taking the time to file a report.  We hope newer versions of Fedora suit your needs.

Comment 15 Francesco Tapparo 2012-07-12 05:27:43 UTC
I'm using fedora 17 now and the problem persists.
