Two kernel panics in ~ 4 hour time frame?

Any idea's on why my laptop is rebooting? Here's the first from earlier today:

I'm not sure what's causing this. I wonder if it happening when my monitor's sleep after inactivity because on both these occasions I was away from desk. Not sure what significance the dhcpd messages have right before each either.

Re: Two kernel panics in ~ 4 hour time frame?

At least for the first post there are at least > 3 minutes between the kernel warning and the reboot.
"i915.nuclear_pageflip=false" might prevent the warning, but I doubt it's related to the reboot.

Re: Two kernel panics in ~ 4 hour time frame?

So strange that these warnings are so close to the reboots. Logical fallacy?

EDIT: I noticed my machine was warm after returning and finding it had rebooted. Maybe if I'd gotten back closer to the reboot I'd have found it hot, because perhaps the CPU was maxing out for some reason related to this and high temp triggered the reboot?

Are they?
You can infer more data from the timestamps of the next boot - also this should probably happen more often?

`journalctl --list-boots`:

 -2 ... Wed 2019-06-12 16:43:17 BST—Wed 2019-06-12 19:58:54 BST
0 ... Wed 2019-06-12 22:23:25 BST—Wed 2019-06-12 23:43:28 BST

... hmm, now I'm not sure whether I'm interpreting this correctly.

This would mean that the machine was rebooting for 14 and 17 minutes wouldn't it. That's doesn't sound right

Re: Two kernel panics in ~ 4 hour time frame?

Seems like it's Lenovo computer in question. I recently had to replace my PS/2 keyboard and mouse to USB keyboard and mouse, because USB-2xPS2 adapter begun to have problems. Actually one adapter works, but it must be connected after booting the computer (not working if connected when booting). Computer: Lenovo Thinkpad T440s.

So if some USB stuff connected, and not necessary for booting, try without that stuff to have some possible causes sorted out.

Re: Two kernel panics in ~ 4 hour time frame?

I assume what happens is that you leave the system, some fancy screensaver shows up, causes the flipping warning and then at some later point the system reboots - maybe failing to S3/S4?
I'd check the power management / screensaver settings and whether you can reproduce this by leaving the system unattended (though still keeping an eye on it)

No, no. Don't have a screensaver. When I said monitors go to sleep, I think the Linux kernel sends HDMI control commands to monitors to put them in sleep.

Yes, I have the dock with lots of USB devices connected. Thinking about it, I have a lot of USB stuff plugged in, and there are keyboard/mouse related events:

A little strange why this hasn't caused problems before though. I'll check previous months journal logs make sure these events are there so to rule them out being new. Also, I just noticed brave-browser is causing core dumps a lot so sosmething isn't right there, but I will need to see if this is happening around the same time as the reboots. Could be unrelated.

Re: Two kernel panics in ~ 4 hour time frame?

I noticed that there are some recent firmware updates available for Lenovo laptops (like mine T440s). The readme-file however tells me that no need to update (my laptop). Also for Lenovo dock (I have Pro Dock) is a firmware update, correcting some issue with external monitor. However installing that dock update requires Windows, and it's unclear if the problem affects Linux usage at all.
