Do you have an Intel CPU? Have you enabled microcode updates?

I have an intel i7 8th Generation. I do remember installing microcode updates, sometime back. I get this output.

Code: Select all

dmesg|grep microcode
[    0.000000] microcode: microcode updated early to revision 0x96, date = 2018-05-15
[    1.021974] microcode: sig=0x806ea, pf=0x80, revision=0x96
[    1.022245] microcode: Microcode Update Driver: v2.2.

Thanks for your help. I wanted to monitor the machine for more. Started using it for everyday things. The freezes started to get more distant like 6 days apart mostly because of me trying to run heavy software which must have increased CPU temperature and caused kernel panic. Just now I encountered 5 freezes back to back. The computer freezed, I powered off, restarted again freezed, I powered off. Happened like 5 times in a row in the span of 15 mins. I am attaching the journalctl logs. Mostly they are the same for the subsequent previous boots. When I print the logs on the console these things are highlighted in the red.
Fixing recursive fault but reboot is needed

Here are the complete boot logs of the freezed boot.

Code: Select all

journalctl -keb -1 
There I watched every one of the virtual products that I opened were under the xfce4-board process(ofcource in light of the fact that I opened them through it) and all were hanged. Like chromium, firefox, some IDE's, and I was getting division flaws when I endeavored to run anything through the terminal. In any case, I was getting division blame when I endeavored to go into the python3.7 translator also.

I have exactly the same issues on my "Dell XPS 15" with Intel i9 processor. Constant freezing of XFCE while running chromium, some IDE's, etc. No segfaults though, just freezing xfce. Sometimes I am able to do ctrl+alt+f2 and kill xfce from there (after which I can start it again and it'll work again), sometimes not. The freezing happens about once each 8 hours.

Any thoughts on how to solve this issue already? It's quite annoying.

I would try out if a kernel downgrade helps

or

if linux-lts helps

then there are also linux-zen and linux-hardened

that makes 4 solution already

and with dowgrading kernels you can go back in time as far as you wish

Might be something different alltogether. But that is the first thing I would test out.

Fast and easy - see tutorials if you need them.

Today, I tried switching to Cinnamon instead of XFCE to see if XFCE is the culprit. Turns out the answer is no. Same freezing issue in Cinnamon.

Using the linux-lts kernel indeed solved the issue. It seems to be an issue with Skylake CPU's. There is a very popular Reddit post on this issue: and an ArchLinux forum post: https://bbs.archlinux.org/viewtopic.php?id=250765.
