The initramfs fails to detect any block devices and drops to the (initramfs) shell. Older kernels (6.14.0-32-generic, 6.11 / 6.8) boot normally because vmd.ko is present. Evidence: - /lib/modules/6.14.0-33-generic/ does not contain vmd.ko - lsinitramfs /boot/initrd.img-6.14.0-33-generic | grep vmd → no results - With 6.11 kernels, vmd.ko is present and NVMe devices enumerate correctly Steps to reproduce: 1. Install Ubuntu 24.04 on hardware with Intel VMD enabled (NVMe behind VMD controller). 2. Upgrade to kernel 6.14.0-33-generic. 3. Reboot. Expected result: Kernel should load vmd.ko, enumerate NVMe device, and mount root filesystem. Actual result: Boot fails, drops to initramfs shell. Only /dev/loop* devices present, no NVMe devices. Workarounds: - Boot older kernel (6.14.0-32-generic, 6.11 or 6.8) where vmd is included. - Disable Intel VMD in BIOS/UEFI (not desirable in many cases). - Recompile kernel with CONFIG_VMD=m. Impact: All systems using Intel VMD cannot boot with kernel 6.14.0-33-generic. Regression compared to earlier Ubuntu kernels. --- To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2126707/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
