Update - Workaround found: The issue was originally on Ubuntu 25.10 with kernel 6.17, where the system would hang completely at "Reached target sockets.target" on every normal boot, requiring recovery mode as a workaround. Upgrading to Ubuntu 26.04 with kernel 7.0 resolved the boot hang, but graphics and audio still required manual intervention.
Root cause: Intel Iris Xe Graphics (device ID a7a1) and Intel HDA Audio (device ID 51ca) are blocklisted in the kernel for Raptor Lake-P hardware (Lenovo X1 Carbon Gen 11), preventing automatic driver binding. Fix: Add xe.force_probe=a7a1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and run sudo update-grub Create /etc/modules-load.d/intel-audio.conf containing snd_hda_intel Create /etc/systemd/system/intel-audio.service to load the audio module at boot: [Unit] Description=Force Intel HDA Audio After=sound.target [Service] Type=oneshot ExecStart=/sbin/modprobe snd_hda_intel [Install] WantedBy=multi-user.target Then run sudo systemctl enable intel-audio Kernel 7.0 fixed the boot hang present in 6.17, but the device blocklisting for both a7a1 and 51ca remains and still requires the above workarounds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2151327 Title: System hangs at "Reached target sockets.target" on normal boot - X1 Carbon Gen 11 - kernel 6.17 - Intel Xe graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2151327/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
