Description of problem:
system report ACPI_POWER_OFF CALLED but don't go off.
Version-Release number of selected component (if applicable):
FC3 Kernel 2.6.11-1.14_FC3
Steps to Reproduce:
1.call poweroff of shutdown -h now
Actual Results: ACPI_POWER_OFF CALLED is the last message - to power
of the machine - I pressed for 5 sec the power off buttom.
On a Dell N-series 370, issuing poweroff from within X hangs the system (can't
switch to a virtual console, but didn't try logging on over the network). If I
initiate a shutdown via acpid (by momentarily hitting the power switch), it goes
Just changed my kernel line in grub.conf to
kernel /boot/vmlinuz-2.6.11-1.14_FC3 ro root=LABEL=/1 rhgb quiet
rebooted, shut down, and achieved power off! Now, can anyone explain
why this works?
AFAIK, "acpi=ht" disables much of the kernel's ACPI support. Maybe that's why
it's working for you.
It would be good to try a kernel with *both* of the following patches applied,
and see if that fixes the problem:
(They're in the Linux ACPI BitKeeper tree, so they'll probably be incorporated
into the mainline kernel by 2.6.13. I have no idea if they'll be incorporated by
Didn't work for me, the acpi=off or acpi=ht parameters just does my kernel boot
freezing very early.

I'm a bit reluctant to patch and compile an kernel tough, I hope those patches
(if fixes) will be incorporated soon.
2.6.11-1.27_FC3 fixes this for me.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
in the meantime i switched to fc4, kernel-2.6.12-1.1398_FC4
problem still exists with this new kernel.

kernel-2.6.12-1.1446_FC5 seems to print more messages, but power off fails again:
Halting system ...
md: md0 switched to read-only mode.
ACPI: PCI interrupt for device 0000:02:01.0 disabled
ACPI: PCI interrupt for device 0000:00:1f.5 disabled
for power-off problem, you should have a look at bug 160775
the problem still exists with 2.6.13 vanilla kernel, the kernel do not poweroff
my machine with the MSI Board.
Mass update to all FC4 bugs:
An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (18.104.22.168). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
Using 2.6.13-1.1526_FC4. Bug still exist. On a Toshiba M50 laptop with Phoenix BIOS.
problem still exists with 2.6.13-1.1526_FC4
Why does entering "shutdown -h now" from the command line works but the
Gnome/KDE shutdown option will cause this problem?
for Comment #16 :
I guess Gnome/KDE shutdown gives the same as the command line "poweroff" (with
possibly options) and doesn't use "shutdown", now the question is what are the
behavious differences between those commands ?
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.
problem still exists with kernel-2.6.14-1.1636_FC4.i686.rpm
a good day for peoples with the mSI MS-6758 (875P Neo) Board.
With kernel-2.6.15-1.1823_FC4.i686.rpm the problem doesn't longer exists.
'shutdown -h now' works for me.
could you please give a look to
