Please check if it works with a 460 driver.

Is pci=realloc needed for this ?

No, resources are properly allocated

Subsystem: NVIDIA Corporation GA106 [GeForce RTX 3060]
Flags: bus master, fast devsel, latency 0, IRQ 18
Memory at da000000 (32-bit, non-prefetchable) [size=16M]

Memory at 90000000 (64-bit, prefetchable) [size=32M]
I/O ports at d000 [size=128]

I guess it’s the known driver bug only. A bios update might be worth a shot.

Bug report with nvidia-driver-460

BIOS version is the latest available.

It’s running flawlessly on Windows though.

That’s driver 470.129. I guess you can’t install 460 from repo on ubuntu anymore, only from runfile (of course, you’ll have to remove the repo driver beforehand).

Can you tell where can I get the exact run file?

460.80 ?

460.80 couldn’t build on kernel 5.15.0-30-generic

Please check if this version works:

Damn, that worked.

Just a final question, so I shouldn’t ever update nvidia drivers?

Sorry one more. WHat version of CUDA will work with this?

I guess it’s 11.4. Just run nvidia-smi, this will show the supported maximum cuda version of the driver.
Since it’s a driver bug that’s known for quite some time now, this should hopefully be fixed anytime soon with a driver update. So once a new driver update gets released, you should check if that fixes it. At least you now have a working driver version to revert to.
