Kubuntu shuts down and reboots in a strange way

[void]

Hello,

I've noticed this problem with both the single-proc 386 and (my current) 2.6.15-686-smp kernels. If I try to reboot via KDE's "End Session" dialog, I find that Kubuntu completely shuts off the hard-drive ~2 sec before actually rebooting back to the BIOS (the HD comes back alive during BIOS hardware detection). The sound is exactly like that of the WinXP BSOD. Neither Gentoo, nor WinXP reboot like this, and I'm concerned it might damage the HD.

Related to this is a shutdown problem that apparently surfaced in early August (and still remains unresolved). Kubuntu is unable to fully shutdown. The very last message is "Sending TERM signal to all processes", after which it shuts down the HD (same eerie sound) but not the CPU. I have to hold the power-off button on my case's front panel to power off the machine.

Has anybody else experienced these problems? How do I go about resolving them?



P.S: I'm not using ATI or nVidia drivers, as I'm running measly Intel 915G integrated graphics

Re: Kubuntu shuts down and reboots in a strange way

I also have this problem and I am looking for a fix myself. I am using ATI but the problem started after the last update I made to Imagemagick and some BING libraries....

Hopefully someone else knows what's wrong.

Please post any solutions if they come up.

Cheers,

Hi I'm also having this problem, though I'd *bump* this to see if anyone's got any solutions??

I'm thinking that it's not very good for my PC that I have to hold in the power button to get it to completely shut down...

You are not the first one in this forum to experience this...

Seems like for Kubuntu to fully shut down you have to add acpi=force to the /boot/grub/menu.lst file. For details see

Hope you find the solution. Let us now what did (not) work for you.

Yep. That's what Windows XP and probably Windows 2000 does when it BSODs. Windows literally does shut down the HDD when it BSODs.

Hi

I think you should run a hard drive diagnostics too see if your hard drive has errors.

If you have a IBM machine they have a diagnostics program for your PC/Laptop.
You have to enter the 7 digits model number to find it on IBM site search.
If checks your whole system.

New HP machine have a hard drive diagnostics tools built into the BIOS.
Most hard drive manufacturers have a drive test program to test the hard drive, that you can download.

You can also buy software diagnostics programs that the PC tech use. They cost $$$

Good luck

I think it is just normal that the hdd shuts down before switching off. The hdd is parking the heads in a fixed position so that the drive is protected from the heads touching the disk if it falls or something.

It shouldn't happen before a reboot though. But that was due to the not working ACPI I guess.

sorry for the delay...

I did as some of the suggestions pointed out by adding acpi=force. I would NOT recommend doing this, when this happened I had a catalogue of very scary errors, one of which meant that I couldn't login in as the .ICEauthority file had corrupted. I resorted to deleting this file (under some *expert* advice) and let the fsck disk check delete all the corrupt files and hoping for the best. Luckily, this worked (??) and only cosmetic KDE configuration settings like programs on the toolbar and favourites had been wiped, and my home directory was intact (THANK god )

For now it seems the best way to shut down the pc is to use the terminal window and type "sudo shutdown -h now"

as a novice i couldn't tell you why the acpi=force suggestion didn't work... I'm just happy I managed to recover my work!

this linux business is bad for my nerves :P

Re: Kubuntu shuts down and reboots in a strange way

Well, my system is no longer exhibiting this bizarre behaviour. I removed the splash option in my menu.lst file and watched the system shutdown. Turns out my mordor game server daemon didn't want to stop. I removed the package entirely, and voila! No more issues.

I cannot explain why this worked, or what was going on. All I know is that you may wish to see if you have any strange daemons (e.g., game, dictd server) running that do not shutdown properly.

Hope that helps.
