UPDATE: Solved! :slight_smile:

Thanks a lot for the quick help, especially @yasirel for linking the launchpad!

What fixed it for me was installing the kernel from proposed 7.0.0-26. For anyone else landing here from a search, heres the short version:

  1. Enable the proposed pocket (official guide: https://documentation.ubuntu.com/project/SRU/reference/enable-proposed/). Quick way on 26.04:
sudo tee /etc/apt/sources.list.d/ubuntu-proposed.sources >/dev/null <<'EOF'
Types: deb
URIs: http://archive.ubuntu.com/ubuntu/
Suites: resolute-proposed
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF

sudo tee /etc/apt/preferences.d/proposed-pin >/dev/null <<'EOF'
Package: *
Pin: release a=resolute-proposed
Pin-Priority: 400
EOF

2.Install the kernel:

sudo apt update
sudo apt install -t resolute-proposed linux-generic
  1. Reboot, and check with uname -r.

perfectly smooth now, no more freezes for me :slight_smile:

Marking this as solved. Thanks again guys <3
