Frequent crashes / hangs with message "GPU has fallen off the bus"

Hello, I am running Gentoo Linux with latest stable nvidia binary drivers with a GTX 3080 Ti. Since I installed the card, unfortunately my computer hangs very often (2/3 times per day) which forces a hard reboot. I’m certain this is due to the nvidia card, as I used the internal Intel GPU before for 6 monthes without any issues.

This almost always happens when using Firefox / WebGL, but I don’t do much gaming on this box so this might be because this is the only program using 3D / the nvidia card.

When this happens, display gets completely frozen, mouse locks, but I still can ssh into the machine from another box. I ran the bug report from such a frozen situation. I attach it as well as the dmesg log which contains a lot of errors related to nvidia at the end. Seems like the important message is [45044.053884] NVRM: Xid (PCI:0000:01:00): 79, pid=‘’, name=, GPU has fallen off the bus.

I hope a nVidia engineer will be able to help / trace this issue. I’ve googled a bit and suggestions are that this may be a hardware / power supply issue. However, in this case it would probably also happens under Windows, and I never noticed it (although tbh I don’t use Windows much on this computer). Also, this does not happen when playing intensive games at all… only desktop work, with as I said very limited WebGL games on some tabs.

This is very, very frustrating having your main computer hang twice or three times a day like that when everything else is fine, so I hope someone can help.

Hello, up? Can I get any advice or recommendation?

I have a similar issue, but with 3090 founders edition, ubuntu 20.04, and drivers 535.104.12

What PSU do you use? Mine is 600W. Could it be not enough for the 3080 Ti?

I use a Super Flower 1000W 80 Plus Platinum

Well then I doubt it is a PSU issue, at least in your case. I dont think it is either for me because this never happens under Windows.
