Rehoot doesn't Restart Linux


Linux Mandrake 8.1 doesn't restart when I reboot. It shutsdown fine. I have to turn off the power for the computer to reboot.

Have tried with several methods and specified the runlevel on the command line. Nothing seems to make a difference.

Any ideas? Thanks

When it is going through the shutdown inits to reboot, are there any failures and what happens just after it finishes shutting down all of the daemons? Could be that something is freezing it at the point it needs to reboot as opposed to shutting down. That's all I got for thought at the moment.

Thanks for the help.

No, everything seems to shutdown fine. No error messages. Things just stop with a dark screen.

Oh... you want it to soft boot. For the machine to go through a reboot all on its own...

Alot of modern boxes have a problem doing this under Linux. Its a matter of getting APM to work right... a number of other things. Basically, unless this is a real hastle its probably more trouble than its worth to try and fix. I've got some starter ideas though if your still curious.

Oh, and does this particular crate reboot right under another OS? I just wanted to make sure it was capable of that trick at all.

Cheers,

I checked the APM in cmos and didn't see anything to change. The computer reboots fine with Win95 and Win98.

The computere is administered off-site, so if it shuts-down someone must go in to turn it on. Coming from Win98 I still can't get used to not having to reboot on a regular basis. Right now we have close to 1 month uptime and I can't believe it!

Thank for any tricks.

Oh, duh, I forgot about the server aspect... Post the motherboard specs and the distro and I'll poke around.

Taz, any ideas?

Cheers,

I'm unsure at the moment...When you say remotely administered, do you mean that you are running as a workstation? What exactly is the relationship between you rebooting and the off-site server? I'm confused about what machine is doing what now. Am I confusing myself? LOL If you could type out the specifications of the problem machine it would help greatly also.

The computer is set up as a web server. To make changes we telnet in to it. While I've learned to just re-start modules, I'd like to figure out why I can't reboot.

Just like if I open the CD through the telnet connection I have to go and close the tray by hand.

The output from "cat /proc/pci" would probably be more than enough for us to figure that out. The idea is to figure out what BIOS era it is in, and also what distro and version is this thing running? It may just be a mater of modprobing something related to APM.

Cheers,

So just exactly how do you do the shutdown? Three finger salute? shutdown command? You said you tried several ways - did you try shutdown -r (reboot). Sounds like (black screen) that it is shutting down with -h (halt).

If you are doing a three finger salute, look at the "ca" line in /etc/inittab and see what version of shutdown is run from there.

Thanks guys. I only reboot using "shutdown -r" and not the reset button. I've also tried "init 6" and still get a dark screen.

Following is the output for cat /proc/pci:

If its not too much of a hastle to experiment, try:

reboot -p now

This won't actually reboot the machine, but will instead tell it to power-off at the end of the init cycle. If it doesn't switch off, then its a matter of the machine not being able to tell the BIOS to restart... or, in this test, to stop it. At least if it can stop the machine, it can tell it something... I gotta learn more about this chipset.

Cheers,

Finegan

Hmm... Sis chipset, onboard video... no USB, firewire, sound... this could be anything. Is it/was it a big name manufacturer? If so, does it have any model info?

"reboot -p" shuts down the computer. The monitor says "Restarting the system" but it just sits there.

The computer is a "no name" and I don't have any info.
