Dell Inspiron - Arch Linux keeps crashing

As mentioned in the topic subject, I am having random hang and then the laptop restarts on its own. If not, I hard-restarts the laptop on own

Please see https://www.pastefs.com/pid/2355 for the log files by the command "journalctl --since=today"
Search for "Reboot" in the paste. I have encountered few hangs in this paste.

Any suggestions ?

Intel Processor?  Have you installed and configured your microcode updates?

Re: Dell Inspiron - Arch Linux keeps crashing

I changed the GRUB setting since I used GRUB.

When I do dmesg, I suspect the microcode is still not updated because I still experience hang as in https://www.pastefs.com/pid/2356

arch% dmesg | grep microcode
[    0.000000] microcode: CPU0 microcode updated early to revision 0x4, date = 2013-06-28
[    0.244478] microcode: CPU1 microcode updated early to revision 0x4, date = 2013-06-28
[    0.925773] microcode: CPU0 sig=0x20655, pf=0x10, revision=0x4

[    0.925831] microcode: CPU2 sig=0x20655, pf=0x10, revision=0x4

[    0.925934] microcode: Microcode Update Driver: v2.01 <tigran@aivazian.fsnet.co.uk>, Peter Oruba
arch%

I have manually installed the intel-ucode package and issue command "grub-mkconfig -o /boot/grub/grub.cfg"

Re: Dell Inspiron - Arch Linux keeps crashing

The only thing I see in your logs is that you are only getting six hours sleep wink
It does appear that at least two of your cores are being updated at boot and that all four of them at at rev 4.  In any event, the microcode updates are a good thing to install.
What is puzzling is that the journal said all four had been at rev 2

Jun 05 00:48:56 arch kernel: microcode: CPU0 sig=0x20655, pf=0x10, revision=0x2
Jun 05 00:48:56 arch kernel: microcode: CPU1 sig=0x20655, pf=0x10, revision=0x2
Jun 05 00:48:56 arch kernel: microcode: CPU2 sig=0x20655, pf=0x10, revision=0x2
Jun 05 00:48:56 arch kernel: microcode: CPU3 sig=0x20655, pf=0x10, revision=0x2
Jun 05 00:48:56 arch kernel: microcode: Microcode Update Driver: v2.01 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

So clearly all four are updating

Saddly, I don't see anything in the logs related to a hang.    You say the system reboots by itself?
Also, at the hang, are the keyboard lights blinking?
Can you log into the box via ssh?
Can you ping the box?

Re: Dell Inspiron - Arch Linux keeps crashing

I have run memtest86+ for testing my 2gB and 4gB RAM. Please see the error count below 1D5b0CQh.jpg. How would you see this? Does this mean I have two pieces of defective RAM ?
