Peppermint 10 freezing
« on: September 14, 2019, 05:18:51 am »
Hey guys!

Saw another tread about peppermint 9 freezing so i decided to make this thread. My OS suddently freezes and i need to restart my PC manually pressing my power button.  This happens only after a few minutes when using Eclipse but also when using Apache Netbeans. This started happening today and it have not been freezing before.

inxi -Fz gives me:

Does it freeze if you boot an earlier kernel ?

Hey!

No it worked fine with Peppermint 9 and also with Peppermint 10 in the beginning, the freezes started happening yesterday. Could it be some software or something that is causing this?

Yeah, but have you tried booting into an earlier kernel to check if it stops freezing .. so we know for sure it's the kernel ?

Do you know how to boot an earlier kernel ?

Which kernels do you currently have installed .. can you post the output from:
Code: [Select]
uname -a
and
Code: [Select]
dpkg -l | grep linux-image

The system has been stable yesterday and today. Strange because it frooze 3 times in a row before i wrote this post.

uname -a gives me:

Linux HP840G2 5.0.0-27-generic #28~18.04.1-Ubuntu SMP Thu Aug 22 03:00:32 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

dpkg -l | grep linux-image give me:

ii  linux-image-4.18.0-18-generic            4.18.0-18.19~18.04.1                             amd64        Signed kernel image generic
ii  linux-image-5.0.0-25-generic             5.0.0-25.26~18.04.1                              amd64        Signed kernel image generic
ii  linux-image-5.0.0-27-generic             5.0.0-27.28~18.04.1                              amd64        Signed kernel image generic
ii  linux-image-generic-hwe-18.04            5.0.0.27.84                                      amd64        Generic Linux kernel image

Well see if it will freeze again or not. And how do i boot to another kernel? Does it remove my files in my "home folder"?

No it won't change the home folder (or anything else).

When booting the PC, as soon as the BIOS POST screen disappears hit the Shift key to display the GRUB menu .. at the GRUB menu, move down to "Advanced" and hit enter .. then move down to the 4.18 kernel and hit enter to boot it.

Once booted, you can check which kernel you booted into with
Code: [Select]
uname -a
if that reports you're in the 4.18 kernel ... check to see if it freezes.



Then again, if it's stopped freezing, maybe you just got a new kernel update that fixed things.

Thanks for the reply! I will definitly try this one out if the problem persists. System has been stable as of last post so hopefully i won't need it.

Okay, i am doing a little update here.

The problem persisted so i decided to try installing another linux distribution called MX Linux but the problem is the same there. So therefore it could not be the operating system.

I decided to run memtest86 and it ran without any errors. Temperatures also seem stable at around 40-48 celcius.

The next thing i did was to update bios from 2016 version to new 2019 version. Problem still persisted.

Next thing i triend was this tip:
https://ubuntuforums.org/showthread.php?t=2354624

Problem still persist. What i have done now is disable DPS or something like that and put fan always on while on AC power. Will see if it works or not.

The strange thing is the computer can run for 4-5 hours without any problems then just freeze..

Nothing worse than an intermittent problem, they're always a b*tch to diagnose.

Indeed!

Update:

I have been running the system stable now the past few days. I noticed that the freezes happened mostly when i was using Netbeans or Eclipse which then must contribute to some problem with Java.

So i reinstalled JDK five days ago and the pc have not hanged since then, hopefully this was the problem. I'll update if it hangs again.

Cheers buddy!

System have now been up and running 4 days in a row with heavy programming and many applications open at the same time, so java was definitely the culprit :). Good for others to know this can cause freezes. 8) 8) 8) :D
