Description of problem:
If the snd_hda_intel module is loaded into the kernel (for example after
starting X), the computer will not power off when "poweroff" command is called.
My computer has an Asus P5GD1 motherboard.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Start computer at runlevel 5
2.Log in into X and play some sound just to be sure sound module is loaded
3.System -> Shut down.
The computer doesn't power off and hangs after a message "ACPI power down
called" is displayed.
The computer shoud poweroff
I added a 'modprobe -r snd_hda_intel' line in the stop) section of
/etc/init.d/kudzu and the computer shuts down correctly therafter.
Changing to proper owner, kernel-maint.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO state.

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
Even with kernel-smp 2.6.18-1.22000.fc5 the problem persists. I tried booting
with the 'acpi=ht' boot option, but the system still doesn't poweroff, the only
thing changed is the last message printed: "System halted" instead of
The only way to let the computer shutdown automatically is to call modprobe -r
snd_hda_intel somewhere during the shutdown process (I moved it from kudzu to
the halt script just after the "saving mixer settings" lines).
I can confirm the problem still exists in Fedora 7 with the Asus P5GD1
motherboard. I've had this annoying shutdown problem for five months and finally
I have found a workaround here, thanks Davide!! Unfortunately I found the bug
still exists in Fedora 8 Test 2 as well.
Changing version to F7 since that it the last released version that this problem
is reported in. You mention F8T2, does it exist in released F8?

This bug is still present in F8 - kernel 18.104.22.168-85.fc8
Could you try booting with acpi=off and then try powering off. Could you also
attach the following from a normal boot as separate attachments to this bug
# lspci -vvxxx

The system with acpi=off still does not power off.
Some more things to try:
Could you try unloading your vmware modules before powerdown. Could you also
attach the output (separate files please) of:

It doesn't power off even without loading vmware and virtualbox modules.
the previous lsmod attachment is without vmware and vbox modules loaded and the
system did not power off.
Found the following which you should be able to use as a workaround:
If you edit /etc/init.d/halt and add “rmmod snd-hda-intel” this will unload the
module and poweroff completely.
I'm assigning anyway and adding ALSA blocker. Lowering severity and priority as
a workaround is available.

I'm already using that workaround since first reporting this bug, so it issn't a
big problem if it persists... :)
Bug still present in Fedora 9 - kernel 22.214.171.124-18.fc9.i686

Davide, could you test the proposed patch for this issue or you need a full test kernel?
Better to get a full kernel if you can.

I have too much work to do, and can't set up a build environment on my machine by now...
The problem seems fixed in FC10.
If somebody else had this issue and tried fc10, please report his results.
OK, marking as fixed for F10. Thanks.
