Title: System fails to boot after upgrading to kernel 6.8.0-86-generic with full-disk LUKS encryption (Dell Desktop) Status in linux package in Ubuntu: New Bug description: Ubuntu Version: No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 24.04.3 LTS Release: 24.04 Codename: noble Problem Description: After upgrading to kernel 6.8.0-86-generic, my system fails to boot with the message: cryptsetup: waiting for encrypted source device... Eventually, in recovery mode, it shows: Gave up waiting for root file system device. This issue only affects kernel 6.8.0-86. Previous kernels boot without problems. My system uses full-disk LUKS encryption on a PCIe NVMe SSD (no SATA drives). This behavior appears similar to a known issue discussed here: https://discourse.ubuntu.com/t/gave-up-waiting-for-root-file-system-device-no-other-os-installed/54932 Current Workaround: I can still boot the system by selecting an earlier kernel in GRUB: 6.8.0-85-generic: works (currently in use) 6.8.0-86-generic: fails (with cryptsetup/rootfs error) 6.8.0-84-generic: previously worked but no longer available in GRUB I am concerned that 6.8.0-85 may also be removed automatically, leaving me unable to access my system. What I’ve Investigated: I found a related AskUbuntu thread (https://askubuntu.com/questions/1350025/cryptsetup-waiting-for- encrypted-source-device-problem) , where users reported the same cryptsetup error on Dell systems. The accepted solution there was to change the BIOS SATA mode from “RAID On” to “AHCI”. However, this does not apply to my situation because: I use a PCIe NVMe SSD, not SATA My BIOS has no AHCI or RAID options available System Information: Laptop: Dell Inspiron 16 (Intel-based) Storage: PCIe NVMe SSD (no SATA devices) Encryption: Full-disk LUKS (default Ubuntu installer) Boot Mode: UEFI Bootloader: GRUB Working Kernel: 6.8.0-85-generic Failing Kernel: 6.8.0-86-generic What I’ve Tried: Rebooted with older kernel versions (84, 85), 85 still works Verified that only 6.8.0-86 triggers the issue Confirmed there are no SATA or RAID BIOS settings to adjust Cross-checked with related threads and known issues ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.8.0-85-generic 6.8.0-85.85 ProcVersionSignature: Ubuntu 6.8.0-85.85-generic 6.8.12 Uname: Linux 6.8.0-85-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Thu Oct 23 17:52:41 2025 InstallationDate: Installed on 2023-09-22 (762 days ago) InstallationMedia: Ubuntu 22.04.3 LTS "Jammy Jellyfish" - Release amd64 (20230807.2) MachineType: Dell Inc.
