Noticed some kind of a bug here in OpenSUSE 11.0 x64, it somehow keeps switching to Runlevel 0 after a few minutes of work, which is quite distracting. Sounds much like Windows’ Blue Screen of death… The bad thing is that I can’t see any error messages or anything - it happens just randomly! Maybe there’s a log about it somewhere? And what can I do to make it stop? Is it a known problem anyway?

Look at /var/log/messages to see what you see in there. Otherwise I’m
not sure… do any other boxes setup similarly do this? Anything in
particular you are doing when this happens? Have a friend/coworker with
a sense of humor?
Good luck.

Here’s the log file fragment between two runlevel 0’s: INI pastebin - collaborative debugging tool
Some info is in Lithuanian, but not too much and not critical. Looks like there are errors like this: “Buffer I/O error on device sr0, logical block #” “WARNING (continueEvent:250) Could not execute program /usr/lib/powersave/scripts for event daemon.scheme.change: No such file or directory” and “kernel: Pinnacle PCTV: unknown key: key=0x35 raw=0x35 down=1”, nothing else it seems. As the current messages don’t state Buffer I/O errors, maybe it could be a problem? Or did I overlook something else?
Any more help? I don’t see how it could happen, it really happens randomly, some times it lasts for an hour, some times for only 10 minutes. It might have something to do with me not formatting /home, but instead mounting it from OpenSUSE 10.2. Or some kind of corrupt software?
Also, despite me getting the Buffer I/O errors, I can read the OpenSUSE 11.0 install DVD normally (it’s the one that was in when I pasted the log).
> Is it a known problem anyway?
no…
sure sounds like a hardware problem to me…
heat would be my first guess…
have you made sure all the fans are turning, and the case has not
filled up with cat hair (or whatever)?
but heat is always my first guess…i’d check for that…and while
the case is open i’d remove the TV card and see if the shutdowns go
away…and of course, it is not so cool to have those I/O
errors…any idea what is causing those?

Well, my Windows XP x64 runs smoothly. According to it’s Device Manager, though, the PCTV card doesn’t have drivers, and I don’t use it anyway. I can try and take it out.
But the strange thing is that in OpenSUSE 10.2 it worked fine. Something must have changed for it to behave like this…
Sorry for a double post, but did some research…
1st boot the system lasted for ~10 minutes.
2nd boot - ~5 minutes.
3rd boot - ~15 minutes.
4th boot (erased all additional boot parameters) - ~20 minutes
5th boot (safe mode) - none (didn’t start because of the x64 system)
6th boot (safe mode without acpi=off) - still lasts (has been ~3 hours now).
So, it seems that something in the safe mode makes it not to shut down. And it is more likely the software problem then.
Also, is there a way to run a disk check from here? I know it automatically checks them if the system fails, but it didn’t do that since the install (the runlevel changes make the PC shut down normally).
i understand your point…but, that list of shutdowns does not, in
itself rule out heat…because beagle is grabbing cycles like crazy
the first hour of the first boot…topping out the CPU and heating it
up nicely…
i do not thik it runs in safe mode (as many other things dont either)
…therefore IF it is a heat problem IT should run longer in safe
mode…
now, i have NO way to know if it is heat there or not…but, it is
the first thing i’d look for…
and, how old is that powersupply…an overtaxed and/or weak supply
can certainly give power spikes which trips the hardware to off as
surely as the power switch…
if you wanna try, yank beagle and beagle helper to a dog house…and,
see if it runs better/longer…
have you run memcheck lately?
of course, it might be software…but look around for yourself (on
this board, or google outside) i’ve not seen another situation like
yours…sure, lots of hangs, pauses, (see:
http://tinyurl.com/6oo8cg) but not full shutdown…
well, you could try 32 bit, ask anyone and they can tell you that it
is MUCH more stable…and, unless you have a million line db or huge
video to render you won’t see much speed increase, if any (read the
fora and check it out) see: http://forums.opensuse.org/search.php

Wow, when I was just about to check the forums, it restarted again! Wasn’t in full safe mode, though, only left the Safe Mode tag and the vga tag in the boot options. Now it seems that Safe Mode prolongs the time, but doesn’t actually stop it from doing things like that… I’ll try to get Beagle out, I don’t like indexing anyway 
Though physically I can’t find any heat there. It’s cold as metal and even some kind of air is blowing out. The PC is brand new, bought this year, so it shouldn’t have any kind of problems, at least with power supply.
No, haven’t run memcheck, how will it help? Or is is like Windows’ checkdisk?
Well, I might need to render something, such as Wine emulated games and such. And don’t think downloading the whole new DVD would be too good, seeing the poor connection I have… (DL speed is at max 40KB/s).
By the way, why does it restart friendly anyway? Like, Windows would bluescreen immediately instead…
> By the way, why does it restart friendly anyway?
i have no idea why it is restarting…it is UNUSUAL at best, and
very very strange–i have NEVER seen it happen here, in years of
using Linux (and other OSs)…
when i say heat/power supply/memory i am guessing…
did you take my hint and see if you can find another single instance
of anyone having the same problem…
it might be a intermittent short somewhere in the motherboard, or
somewhere else in the system (like, the reset button on your computer
is nothing more than shorting two pins together momentarily, which
signals the machine to shutdown…buttons FAIL, wiring gets loose,
contacts corrode etc etc etc…)
i am guessing it is hardware…but, you are more than welcome to
see if you can google up a software cause, and fix it that way…
if you don’t find a software problem you might try your friend google
for hardware help…a quick search on
computer hardware troubleshoot guide
brought millions of hits…the first,
http://www.daileyint.com/hmdpc/manual.htm looked real
interesting…but, i didn’t spend a lot of time looking at it…my
stuff is working 
good luck.

I can’t see if anyone has a problem like this, as it’s a home PC, and I know only a single other PC that is running Linux anyway.
Though it seems that with the dog disabled (both in desktop and in Firefox) it works for at least longer. Can’t say if it works for very long, but so far it works for 1 hour…
Oooh!! Just as I was writing this… I changed my KPowerSave setting earlier, Power Button → dialogue rather than power off… And I just got the dialogue! No more forced power offs! That might give a hint on that… Something making OpenSUSE think that the power button was pressed?
Anyway, no more forced restarts! Only a dialogue! Yay!
> Something making OpenSUSE think that the power button was

could be…(as mentioned earlier: the shut down signal is a momentary
shorting across two pins…you could have a pinched wire touching the
case or a hairline crack in MB or a little bit of corrosion in some
connection or a static electricity zapped something somewhere or or
or or or or )
or a power spike from a weak or failing power supply…see, what
many don’t know is that some (many? most?) computer builders use the
VERY least expensive components that they think will last long enough
to get the whole system to the end of its warranty life…and,
after that the do NOT care…
they buy the very cheapest power supply (and fan, memory, heatsink,
memory and and and) they think they can get away with…JUST big
enough to power the stuff in the box they sell…so, if you add a
hard drive or two, a few external (UBS) things, a fancy video card
etc etc etc, it is pretty easy to overtax the born with power supply…
do that and it burps…it does not take very many millionths of a
second of NO or NOT ENOUGH power for the system to just quit!!

But then why on OpenSUSE 10.2 it never happened? Nor in Windows XP?
Intresting problem and good idea to enable the dialog for kpowersafe. You wrote “never happened”, I asume you can no longer boot into 10.2 but can you still dual boot to XP ? If so and it still is fine there then I cant see it just being a hardware issue…
Yes, that’s true, I cas dual boot to Windows XP x64 edition, and OpenSUSE 10.2 x86_64 was overwritten by OpenSUSE 11.0 x86_64. And only this version erroneously gets shutdown signals.
what would happen if you change the runlevel to 0 in linux

if you swich the runlevelto 0 i need to know about runlevels al info.

A Google search for “linux runlevel 0” would seem to provide your answer.
