Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Recently I installed Ubuntu Feisty Fawn. At the beginning everything was ok, but a few days ago it started crashing very often - once an hour or so. I suspect it's connected with firefox. I have installed quite a few programs. I also installed a lot of plugins for firefox.
I noticed that whenever I'm running the firefox browser it's crashing more often - everything just freezes and nothing can be done apart from pressing power down button on my computer.
Is there any way of tracking down the reason? I suppose, it's not easy. Is there way of removing firefox AND everything connected with it(ie. plugins). Then I would be sure if firefox is the reason for crashing.
How did you install Firefox? If you used (a) the package manager, then use that to uninstall it. I don't use Ubuntu, so you'll hafta check the manual or docs for the package manager. Typically its the same command as when you installed it, except with an '--uninstall' or '--remove' flag added. The plugins should become defunct automatically when Firefox is removed.
If you really suspect Firefox, you can start it in safe mode to experiment. type 'man firefox' or 'man firefox-bin' in a console for possible instructions.
Check your system logs (probably in /var/log) for any indication of what went wrong.
If the problem persists, post some info about your machine as well, like the processor type, laptop/desktop, that sort of thing. (EDIT: OK, I see some system basics in your signature.)

I have Intel Pentium D 820, Nvidia 7600GT, 2GB RAM
Ok, It may not be Firefax after all, I don't know.
The computer was up for around 1 hour. I played quake (20 minutes), ran LightZone(10 min) to process some photographs, opened the terminal, everything was ok. I did not run firefox. Then I decieded to apt-get epiphany. I ran it, browsed for 1 - 2 minutes and it crashed, was not responsive at all. I restarted the computer and checked the /var/log/messages - nothing that would indicate any error. The only thing that seems wrong are the following lines(which takes place during bootup):

It has been there since I installed Ubuntu and Nvidia drivers.
The thing is that everything was ok for about 2 weeks.
I don't actually know what it can mean
The nVidia errors are nothing to worry about -- they are due to nVidia neglecting to completely code the i2c-bus support into the binary drivers. It is supposed to be fixed in a next release.
So -- Is this a laptop? I'm suspecting it is, but please correct me if not.
I am looking at the APM/ACPI messages there.. They too may be insignificant to this crashing issue, but it makes me suspect something is amiss with the ACPI system, and/or the machine might be overheating, or atleast 'thinking' it's overheating. And actually, *maybe* the video card is overheating.
Does the machine have adequate cooling, clean working cooling fans, etc?
It appears that the issue happens when you have had it under a load for a while, yes?. Is this stuff from your 'dmesg' ??
thanks for the reply
sorry, forgot to add: not it's not a laptop.
But you may be right about overheating. Before I installed ubuntu, I changed the processor from Celeron to this dual-core pentium and initially had problems for one hour because the computer could not start - the processor was not cooled down properly. I took out the heatsink and put it back again properly, which has worked.
Both the processor and the gfx card are brand new with clean fans, the computer is 'open' all the time. I didn't put back the case.
I used synaptic and removed anything connected with firefox and epiphany.
For the last 20 minutes I've been running:
googleearth, gimp (with 2 raw images opened), billardGL(3D),openoffice word, terminal, bluefish, celestia (3D), lightzone (1 highquality raw picture opened), chess, flightgear (3d flight simulator), gftp connected to a server.
On top of it I tried to run quake openarena. It did not run smoothly. I quit it after 1 min. The thing is it did not crash. I've been playing with the programs for the last 10 min.
(I presume these are: motherboard, cpu1, cpu2?)
I also ran the nvidia settings program which gives the temp of 51C (after quitting quake 52C)
The message was actually from /var/log/kern.log
edit: my kernel is 2.6.20-15-generic
edit2: it's still running, everything is ok, the system monitors shows the cpu history. Both CPUs have been at 99 - 100% for the last 20 min.
It it still working
Do you need any more info. Again I'm inclined to think that it was FIrefox or one of the many plugins I installed recently.
what do you think?
Well, it would 'appear' to be a heat related issue.
As far as the temp readings you are quoting, where are they from? The BIOS, or from LM_sensors, or where? I ask because unless you have whatever tool it is FULLY configured, the readings cannot really be trusted. The BIOS is the best thing to use, but of course it's pretty difficult to load up the machine when looking at the BIOS screen .
Finally, did you update/replace the BIOS such that it is aware of the new CPU, and capable of dealing with it properly? That sounds like a significant CPU upgrade
I have no comment about the Firefox issue, that does seem strange..
Chances are, from those numbers, temp3 is the CPU, temp2 is the system, and temp1 is either the CPU socket OR the North Bridge IO chip. No guarantees, but thats how it looks.
And yes, I think you should reinstall Firefox and proceed like you always have, and see if the problem returns. that would pin down Firefox for sure. As to what it might be doing when you're not looking, that would cause the system to crash, I'm still at a loss there
Personally, I would be hesitant to trust those values for temperature. They just don't look right.
It is next to impossible for the motherboard, or 'system' temperature, to be higher than the CPU temp. The CPU temp should be the hottest temperature of all temperatures indicated in a BIOS. The fan speed looks reasonable though.
Well... I'm not totally sure.. But because of the CPU change and the questionable temp readings, somehow it must be determined whether the machine is ACTUALLY overheating (which it's not likely Firefox could do all on its own) OR if there is a screwy system call or BIOS call (like in the ACPI system, or that "CPU Internal Temperature Control"..
You, as the owner of the machine , are fairly comfortable with it, as in, how it works on a day to day basis, what little quirks it has, etc.. So, let me ask: "Do you really think the machine is overheating?"
Personally, I do not, but this is YOUR machine, so you hafta do what you think is going to help figure it out. Here's what I would do, if it were MINE though:
1 - At all times, have the temperature readings you are using visible, if possible, so you can watch them. Even if they are wrong, they still change up and down right? So an anomaly will appear if it happens.
1.5 - Turn on ACPI 2.0, and use the machine as you normally would. Watch for anything different.
2 - Try Disable the ACPI completely, and repeat as above.
3 - Disable the CPU Temp Auto Temp Control. Reboot and repeat as above.
Is there ANY OTHER BIOS functions or selections, that are either 'high-tech looking' or that you aren't sure what they do?
Again, I find it hard to believe that firefox can overheat a machine like this, especially after you having ran all that other stuff at the same time and had no problems.
Meanwhile, do you still have firefox installed, MINUS its plugins? That would be good, and to try that for a while --- and if it crashes again, well... Mysteries of the unexplained, but I would start Googling for similar complaints, search The Intel website for anything about that CPU, research the motherboard for similar problems, and the BIOS - Google for similar troubles there too. Plus, wouldn't hurt to check out the mozilla bug forums I suppose; though, well who knows what you might find.
Lots of searching, I know, but.. Maybe someone around here with a bunch more hardware experience than you or I have, will have some ideas .
Keep us posted!
