1 month ago Ok I sorted it out (finally): when Ubuntu updated from 22.04 to 24.04 it kept the vrwa.service, but never enabled it again. Details are here.
The vrwa.service is located at /lib/systemd/system/vrwa.service and contains this script:
[Unit]
Description=vrwa Service
After=multi-user.target
[Service]
ExecStart=/usr/bin/bash -c 'echo device_specific > /sys/bus/pci/devices/0000:2b:00.0/reset_method'
[Install]
WantedBy=multi-user.targetI enabled it with systemd:
systemctl enable vrwa
Vendor-reset no longer working with Ubuntu 24.04 and Linux kernel 6.8.0-41. MSI B350 PC-Mate motherboard with Ryzen 3800, nVidia 1050TI for Host and Vega56 for passthrough to Guest.

Installation went like this: cd /usr/share git clone https://github.com/gnif/vendor-reset.git cd vendor-reset dkms install . Sign command: /usr/bin/kmodsign Signing key: /var/lib/shim-signed/mok/MOK.priv Public certificate (MOK): /var/lib/shim-signed/mok/MOK.der Error! DKMS tree already contains: vendor-reset-0.1.1 You cannot add the same module/version combo more than once.
I guess it must have kept the installation when I updated Ubuntu 22.04 -> 24.04? modprobe vendor-reset modprobe: FATAL: Module vendor-reset not found in directory /lib/modules/6.8.0-41-generic
Can it be removed? rmmod vendor-reset rmmod: ERROR: Module vendor_reset is not currently loaded
sudo dmesg | grep reset [ 11.540639] vendor_reset: loading out-of-tree module taints kernel. [ 11.540646] vendor_reset: module verification failed: signature and/or required key missing - tainting kernel [ 11.570389] vendor_reset_hook: installed
I wonder if anybody has any advice about what I can do here. I feel like I messed up something that's probably very straightforward to resolve, but I don't know the specifics.
Thank you for helping!
