since the kernel upgrade to 2.6.11-1.14_FC3 my motherboard doesn't turn
the power off after the shutdown processus.

the runlevel shuts down all the daemons, turns off the disks but the
power still remain on the motherboard, so that you have no display, no
working mouse or keyboard, no spinning disk, just the ATX power and the
motherboard with power on but the machine seems dead.

pressing the power button doesn't change a thing, even if you press it
for one minute, you have to pull the cord out...

tryed to use acpi=force at boot time, no change

tryed to toggle enable/disable the "ACPI v2.0 support" in my motherboard
bios settings, no change.

the same happens if you shutdown with the gnome panel menu Shutdown or
press once the power button, the runlevel runs fine but power remains at
the end.

Everything was fine since fedora core 2 and all its kernel upgrade and
fedora core 3 upon 2.6.10-1.770_FC3.

For information my motherboard is a Tyan Tiger K8W, more at

I have read some threads in the mailling list about the kernel being instable for some people, I'm wondering if something isn't very wrong with the ACPI since this kernel version.

I am ready to make some tests or give more informations if needed.
