Suffering occasional system freezes

[ian_r_h]

Hi, all,

Since Sunday before last, I've had three apparent complete system freezes.  The first was during a DVD write, and I am confident it was a system freeze rather than a simple graphics freeze (with the system still running), and the DVD write did not complete despite leaving it 20 minutes (it normally completes in 5 or so).

Being new to Linux, I was wondering if anyone has any advice on how to go about diagnosing such freezes - for example, which log files to check, what terminal commands to try, etc.?

Thanks,
Ian

Being new to Linux, I was wondering if anyone has any advice on how to go about diagnosing such freezes - for example, which log files to check, what terminal commands to try, etc.?

Since there might be a number of reasons for that to happen, it's really hard to tell/advice about how to proceed without being in front of that pc. However, there's plenty of info on google and running a search with the right terms should be the first step, I know, easier said than done, cause sometimes those "right terms" are not that clear to us specially when we're not sure on what we're looking for. In your case I googled for "ubuntu freezes" and "view logs in linux",  this brought up some interesting results. Read and see if you find something that may help with your issue

It's a lot of reading I know but I'm sure not only you'll learn quite a few interesting things but also find something helpful in any of those articles/posts that will help you in diagnosing/resolving your issue, so next time you might tell us what to do when facing a similar situation

Hope this helps!

Thanks, Moltke,

My next immediate plan of action was indeed to do those very same searches.

I'll report back should I find the solution (or at least identify the cause).

My immediate hunch is it's possibly a problem between the Linux Kernel and whatever graphics driver this unit is running - as before a recent Kernel update I was getting obvious graphics problems but not a system freeze; whereas now I am getting system freezes and none of those obvious graphics problems.

But I'll see what turns up.

[ian_r_h]

Well, I can immediately rule out something simple like a recent theme change.  Changed it back, and it froze again.

The meantime between freezes is on the order of 16 hours.  This is worryingly frequent, given my backup model assumes crashes on the order of a meantime of 28 days or better.

Also, the nature of the lock-up is requiring a hard reset; which I'm guessing carries a per-event risk of corruption possibly requiring a rebuild.

So far, I have tried:-
1)  CTRL-ALT-DEL.  This has no effect.
2)  Enabled sudo sysctl -w kernel.sysrq = 1 ahead of any freeze and verified by sysctl -a.
3)  ALT+sysrq R E I S U B (ten seconds between each letter) had no effect.
4)  Tapping the power button had no effect.
5)  Had to hold the power button to hard power off the computer.

To begin diagnosis, I propose:-

1)  Recording the exact time of the freeze from the panel clock, which I've set to include seconds.
2)  Check the main event log /var/log/syslog at that time to look for any error immediately prior to the lockup.

And continuing Googling.

One quick question - is it possible to boot into an earlier kernel version to see whether the problem continues, and if so. how?

Would I need to boot into the latest kernel before updating system and software?

Thanks,
Ian

Hi [member=7114]ian_r_h[/member]

One quick question - is it possible to boot into an earlier kernel version to see whether the problem continues, and if so. how?

Hold down the "shift" button while booting, this will display the grub menu where you can select a different kernel to boot from. Out of curiousity, what kernel version are you using?  Open a terminal and run

Code:

$ uname -r

this will tell what kernel version you're system is using.

Would I need to boot into the latest kernel before updating system and software?

I'm not sure I understand your question but, unless you've installed a newer one, I think that "the latest" available kernel at the time LL was released is already installed in your system and it's the one it boots from, a newer version is usually installed when updating if available. However, if you want to try a new one go here: https://www.freecinema2022.gq/forums/linux...ernel/270/ 
There you'll find instructions on how to install kernel versions 4.11 to latest 4.14 as well as older ones.
By the way, I completely forgot about it but there's a tool in LL for viewing logs called "system events" or something like that, - my language's spanish - Look for it in whisker menu on system entries.

Hope this helps!

[ian_r_h]

Gracias, Moltke.

(I've just started learning Spanish, as I have access to a native speaker at the moment!  But that is pretty much the extent of it at the moment.)

uname -r reports that I am using 4.4.0-102.generic.

I had tried compositing and have a hunch that it might be that which has been causing the system freezes.  It certainly seems to be one common cause.  I've now disabled it and will see how it goes first (as well as doing a memtest check from a DVD live boot).

Thanks for the info on booting from an earlier kernel if available.

My question is that when it comes to updating, presumably I need to boot from the current kernel (4.4.0-102-generic), rather than booting from an earlier kernel?

Thanks, again.

Hi [member=7114]ian_r_h[/member] an

My question is that when it comes to updating, presumably I need to boot from the current kernel (4.4.0-102-generic), rather than booting from an earlier kernel?

  There's no need to change the kernel LL boots by default, at least I have never needed to not in LL nor in any other distro I've tried.

Next time your system freezes, hope it doesn't but if it does try the following, press "Ctrl+Alt+F1" this will take you into a command line mode, give it a couple  of seconds and then press "Ctrl+Alt+F7" which will take you back to your desktop. If it works and your system is no longer froze then we can think of possibles causes.
You could also try a newer kernel version. Also, would you mind doing a system report with LL tool for that and attaching it here so people can take a look at it and help in diagnosing your issue.
Hope this helps!

[ian_r_h]

Thanks again,

Just swapped back to the offending laptop for live use - so will now find out whether the problem was caused by compositing or not!

Hi [member=7114]ian_r_h[/member]

Thanks for the system report, let's hope someone take a look into it and provide some input. All I see is that laptop uses Sky Lake Integrated Graphics and reading on the web I found some people reported having problems with it while others stated it worked just fine. Just one thing, next time when asked for attach something use the option for that which is placed just bellow the reply box 

It is well explained here https://www.freecinema2022.gq/forums/intro...uidelines/

I found this https://wiki.ubuntu.com/X/Troubleshooting/Freeze I think it might be of some help in diagnosing your issue. The article explains how to proceed on different scenarios for debugging system frezzing issues.

Hope this helps!

Thanks, again, Moltke.  And duly noted for attaching system reports, etc.
