Cannot reboot FC5 on ASUS P4S8X/Celeron D
None of the commands that would lead to a reboot are successful (e.g., reboot, shutdown -r now, init 6, etc.) The machine hangs after issuing "rebooting system." The keyboard lights flash as if the box were going to bounce but it just never follows through. Could APIC/ACPI have anything to do with it (see below)?
Any help is greatly appreciated!

My guess is you have answered your own question. Try the
Code:
acpi=off If that works and you want to make the change permanent, you can add the parm to /boot/grub/grub.conf on the kernel line. |
I've already tried that one with no success. Does the APIC service/daemon have anything to do with this? (I guess it is pretty apparent I have essentially no idea what APIC/ACPI is. Can anyone enlighten me?)

Haven't seen a problem like that since back in the 2.6.12/13 timeframe.
What kernel level are you ???. |
Everything on the box is up to date: Kernel = 2.6.16-1.2133_FC5
|
Also try the
Code:
noapic |
I really appreciate all of the suggestions. All of my efforts have been in vain, though. I would really like to learn something from this experience anyway: what is APIC/ACIP? Why might one or the other cause this problem? Why might one imagine that disabling one or the other would help?

I am having the same problem, although my servers are FC3. The only way I can reboot is by connecting a PS/2 keyboard to the servers. Does any one has additional suggestions on how to troubleshoot this issue?
Thanks, David |
Fixed
Added to boot parameters: reboot=bios.
