Significant loss of speed after the update

[Lutti]

After updating with

sudo apt update
sudo apt dist-upgrade
sudo fwupdmgr refresh
sudo fwupdmgr upgrade
sudo reboot

to version 580.159.03, I’m now only getting 25 T/s with qwen3.6:35b; previously it was > 60 T/s

Under load according to NVTOP, it runs only at 565 MHz and 10 W; under idle, it runs at 2021 MHz

How can I reinstall the previous driver?

just try to unplugged power cable from your spark for around 30sec

I just ran tool-eval-bench on my “go-to” model, and it is performing a slightly higher score than before that update. Not all performance metrics were better, but median turn time is down.

Everything’s fine again, thanks a lot.
