Debugging a system crash

[LAPB]

Hai, i installed sabayon the saturday, and i didnt know where else to post, so here it goes..
My system freezes every once in a while. i had this problem with mint (see http://forums.linuxmint.com/viewtopic.php?f=109&t=130440) on kernel 3.5.0 and then i decided to update (not specifically to fix this) to 3.8.10 still happened, both kernels 32 bit. i didnt have much luck, so i gave up for a bit. then i found sabayon and the saturday installed it. the sunday i came to realize my cpu was 64 bit capable, so i switched to 64 bit edition, it still happens. i havent been able to tell what special thing im doing when this happens, but heres the you could say symptoms:
- lock keys (num/caps/scroll) dont work
- following key combos dont (although im not really sure) work: ctrl+alt+del/backspace, ctrl+alt+f1, alt+print, screen/sysRq+reisub. will check next time
- once i was listening to a song and the sound looped
- other times it outputted static
- the leds (num/caps/scroll lock) dont change their state
- a friend told me to use windows for a week and see if it happened, im not sure anymore but, it didnt
once or twice it just rebooted instead of freezing

correct me if im wrong:
- ctrl+alt+f1-f6 ---> switches to virtual consoles
- ctrl+alt+f7/f8 ---> switches to the console in which X is running
- ctrl+alt+backspace ---> Kills X
- ctrl+alt+del (supr on latin keyboards) ---> Signals the init process (usually configured to soft reboot)
- altGr (this has to be used instead of alt else a screenshot will be dumped) +print screen/sysRq+<key> executes a command (possible keys and their commands available in Wikipedia)

if all this fails it can be safely assumed that the kernel died?


how can this be further debugged?

oh and im using KDE

thanks in advance and hope this also helps someone

Welcome to the Sabayon forums.

It will help if you can give details of your system and which version of SL (I know you have mentioned KDE but did you install from a recent iso and have you updated?).
The logs that may hold a clue are dmesg (type dmesg into your terminal), kdm.log, rc.log, Xorg.0.log (the last three are in /var/log and I recommend

Code: Select all

kdesu dolphin

to copy them somewhere to look at). There is also .xsession-errors which is in your home directory (you need to have "show hidden files" checked).
I may well have missed something but I'm sure someone else will correct that error.

At a guess it sounds as though you may have a hardware problem - something as simple as a loose connection or something as serious as a failing capacitor on your motherboard.

Hai and thanks

i couldnt get the 13.04 iso to boot (topic for another report, i thought it was my pc but then someone on irc had the same problem, hoping for that person to report the problem) so i used the latest daily build, and installed KDE edition from there, i performed a full system update right after installing

ill keep dmesg, kdm.log, rc.log, xorg.log and xsession-errors in mind

when this happens again should i boot from a liveCD (USB in my case) or mint, so the logs dont get polluted with other stuff?

[LAPB]

ok it happened again, sadly i did boot into my system cause it happened during a system upgrade that included KDE4.10.3,
i didnt wanna log into KDE to see a half updated DE, so logged into fluxbox, i was thinking more about trying to recover the half upgrade, so i forgot to boot into a live system.
anyway no key combo worked, not even magic sysRq, can i assume that the kernel died?

I built a computer several years ago, and it crashed sometimes. I tried reseating cards and memory sticks, and checking my connections, installation issues, etc. But the crashes continued, usually after using it for at least 10 or 15 minutes, sometimes a half hour. I removed one of the memory sticks and it did not crash. I swapped the memory sticks and it would not boot. I checked it several times and I became convinced that one of the memory sticks was bad. I deduced that the crashes were occuring when memory use exceeded the first stick and started using the second one. I have not have any trouble since I replaced that memory stick.
Just a thought, and easy to check.

this time somthing different happened i came back from dinner and my system was put to sleep and the screen had been locked (i know cause i configured it that way) so i press a key to wake it up blank/black screen for a little while, during that while i tried to see if it was "alive" i pressed a lock (num/caps/scroll) key, and the led didnt switch its state, then the cpu beeped and the screen showed me something not too different from this but in colors, basically corrupted graphics, i tried the magic sysRq combo but it didnt work. this had happened like a couple of days ago but im not sure its the same problem

PD: why do i always forget about the logs? >_>, anyway i wasnt too late now

It all seems very like a hardware failure to me. It may be a good idea to run a thorough memory test.

hmm hardware failure...., makes sense

ok this time i remembered to get the logs

kdm.log
dmesg
rc.log
Xorg.0.log
xsession-errors

Would like to join in.

Installed Sabayon 13.04 (all editions tested... huh), upon logout I have ~50% chance for it to show a dark sabayon background and a blinking _. The graphical part of the system crashes once in a while. Throughout one day it crashed at least 3-5 times. There I can switch to ttys, and log into root and do a 'reboot'.

Same on my friends' PC, and hardware is not faulty.

There are some other less serious but still annoying things about this distro for me but I still want to make it work. Most convenient of all in my opinion...

You probably should start your own thread, or it gets confusing as to which problem we are working on. At any rate, I would suggest you give some details about your hardware, especially, your video card, but also DE (Desktop Environment, such as KDE, or Gnome, etc.). Video card information can be found by issueing this command at a root prompt:
lspci
Then look for the line that starts with the letters VGA.
Mine looks like this:
01:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce GT 240] (rev a2)
