I’ve watched these freezes for 6 months and it seems to me to be associated with whonix-ws-16. At least, the most consistent freezes occur when I start anon-whonix and use for a few minutes. I very rarely get freezes without anon-whonix being opened, but it does happen. I can’t figure rhyme or reason why it happens.

Sharing an anecdotal experience of mine: the frequency of the freezes I reported in this thread seems to have decreased. I haven’t got a total system freeze on me for some weeks now, even though during the time I had my machine working day and night, doing backups, working idle, etc.
So that’s encouraging. Thanks to the QubesOS dev team!

The only freeze and hard reboot I am experiencing now happened when doing qubes-dom0-update. Otherwise my Qubes 4.1.1 is stable. Using 6.1.12-1 kernel a xen 4.14.5 (after reboot).
Qubes OS if very unstable in my case. Unfortunately, I’ve had enough, I can’t recommend Qubes.
First, desiring to get rid of the reboots, I changed my RAM, CPU, motherboard, and power supply. Now I understand that the problem is in the OS. It’s crashing without any signals in the log, mainly on virtual machine start/stop.
So I still can’t boot into the system at the first time! Usually I am trying to boot five or more times to start all my appVMs. Then I am trying to keep my computer uptime 24/7, that is usually a week without the accident reboot. Starting an appVM turned into a reboot lottery.

I’m sorry you have had these problems. Thanks for trying so hard.
It would be helpful if you could share details of the hardware you have
used.
There is a hard regression in 4.1 that results in these problems for
some users. In some cases this seems to be linked to Qubes
starting/shutting down, and perhaps memory usage. In some cases there is
no log evidence.
It may be that these problems are resolved in 4.2, so it may be worth
your while checking in now and again and trying that release.
I hope to see you again.
Have you tried/tested kernel-latest? - if no, would you be willing to test it?
sudo qubes-dom0-update --disablerepo=* --enablerepo=qubes-dom0-current-testing kernel-latest
(in Dom0)
If you have issues booting, could you try temporally adding:
qubes.skip_autostart
to the kernel line at boot (hit e to edit the GRUB config, use the arrow keys to locate where it says quiet and replace it with qubes.skip_autostart)?
Maybe relevant for some coreboot users: Bug #121: T520: Hangs in OS - coreboot - Issue Tracker

I would like to report that my intel i7-3520M CPU (on Thinkpad X230) has been rock-solid stable since a month. I am on Qubes 4.1 with the latest updates installed. I have been using my setup for video encoding day and night and never had a freeze so far.

Ditto. On a Librem 14. Used to be that I had to have power-adapted plugged in for updates, but rock solid now.

The Qubes OS stability has increased significantly since last dom0 update. No single crash and reboot since then.
I’m even nervous about that

Since the week of July 29th, 2022 Update, QubesOS freeze, crash and reboots.
And I created this topic on the forum.
Today, August 18, 2023 and many updates later the same still occurs. I have never been able to find what caused the crash since July 2022. Before that period I never had QubesOS crash.
It happens when I move or drag a windows over the screen. Sometimes it happens. Sometimes it does not. Can it be related to a refresh rate, or a lag or something?
My solution is to avoid moving or dragging screens, but in the case a window opens partially outside the screen and you need to drag it to see it. And then it often crashes. But I have no choice.
As an update during July 2022 caused the issue, I was hoping for it to be resolved by now. But a year later and it still happens.
Does it crash if you right click on the window, choose “Move” and then press arrows on the keyboard?
(It never crashes on my Librem 15.)
Are you on i3 by any chance? Your post was a long way back in this thread and a number of useful “fixes” have been posted for this since then.
It happens when I move or drag a windows over the screen. Sometimes it happens. Sometimes it does not. Can it be related to a refresh rate, or a lag or something?
I seemed to have eliminated this by changing:
Window Manager → Focus → Focus model → Delay before window receives focus:
move it all the way left, then tap the right keyboard arrow 25-50 times to make it 25-50 ms.
I use focus follows arrow, but I’ve noticed it gets buggy when mouse focus hops back and forth very quickly between two windows (which occurs during resize).
My main problem right now is gntdev.c:406 errors are filling journalctl.
I was haunted by kernel freezes when using salt for about an half year. A few mount ago the issue disappeared, probably because of an kernel update.
I use i3wm on a Lenovo T430 with Heads.

For me they disappeared when switching from a self-build HEADS version to one from the Nitrokey repository.
Interesting, I was on the Nitrokey version all the time.
