Dear Maintainer,

The bullseye-backports kernel seems to have memory leaks.

![Memory Basic 1](https://img.bgme.bid/media_attachments/files/109/765/807/240/058/094/original/4797799a06a1f6a0.png)

The memory usage graph during the worst memory leak.  But unfortunately, it was restarted directly at that time, and no log was kept.
