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. 

-- Logs --

-- Additional Information --
No custom kernel parameters or modifications have been applied. The issue occurs with the default installation and kernel provided by Debian 12.7. Let me know if further logs, dumps, or tests are required to assist in diagnosing this issue.
