Package: src:linux Version: 6.1.0-28-amd64 Severity: critical
-- Description --After installing Debian 12.7 (Bookworm) using the official netinst ISO, the system encountered a Kernel Panic during a shutdown or reboot when the `mdadm` utility was resynchronizing RAID devices.
The issue occurs consistently if the system is restarted or shut down while a RAID array is in the process of syncing. This behavior leads to an unrecoverable Kernel Panic, rendering the system unbootable without manual intervention.
-- Steps to Reproduce -- 1. Install Debian 12.7 from the official netinst ISO.2. Configure RAID1 arrays using `mdadm` across two NVMe devices (`nvme0n1` and `nvme1n1`).
3. Allow `mdadm` to begin syncing the RAID partitions (e.g., `md3`).4. Initiate a system shutdown (`shutdown -h now`) or reboot (`reboot`) while syncing is in progress.
5. Observe that the system encounters a Kernel Panic during the process. -- Expected Behavior --The system should cleanly handle the shutdown or reboot process and properly stop all active RAID operations without triggering a Kernel Panic.
