Public bug reported:
System: Lenovo ThinkPad X1 Carbon Gen 11
Ubuntu version: 25.10 (Questing)
Kernel: 6.17.0-22-generic
Graphics: Intel Xe (integrated)
Problem:
System hangs completely after "Reached target sockets.target - Socket Units" on
every normal boot. The system is not fully frozen as Ctrl+Alt+Del triggers
reboot. No further boot messages appear on screen after sockets.target.
Workaround:
Booting via GRUB "Advanced options" → Recovery mode → Resume works and produces
a functional desktop. Recovery boot cmdline: ro recovery nomodeset dis_ucode_ldr
What was tried:
Multiple kernel versions (6.17.0-14, 6.17.0-20, 6.17.0-22) — all hang
identically
Kernel parameters: nomodeset, i915.modeset=0, i915.enable_psr=0,
i915.enable_dc=0, dis_ucode_ldr — no effect on normal boot
Downgrading intel-microcode to 3.20250512.1ubuntu1 — no effect
Blacklisting btusb — no effect
Observation from journalctl:
Last logged entries before hang show Bluetooth firmware loading successfully,
then silence. The i915 driver does not load in recovery mode
(simple-framebuffer is used instead).
