Package: linux-image-6.12.29-amd64
Version: 6.12.29-1

Hello maintainers of the kernel,
The new kernel (6.12.29) has a modified behaviour (compared to 6.12.27) for the loop device. 

This causes the Debian live images (for sid) to fail to boot.
The change happened between 20250518T201633Z and 20250519T021902Z, which matches the upload of 6.12.29 (https://tracker.debian.org/news/1646619/accepted-linux-signed-amd64-612291-source-into-unstable/) at 20250518T230426Z. 

To reproduce:
* Download the daily live image from https://openqa.debian.net/tests/396941/asset/iso/smallest-build_sid_20250519T021902Z.iso 
* Boot into the live image (the first boot option)
* Result: an initramfs shell (instead of a live system) -> FAIL
* Try: `losetup -r /dev/loop1 /run/live/medium/live/filesystem.squashfs`
* Result: `failed to set up loop device: invalid argument` -> FAIL
* Try: `cp /run/live/medium/live/filesystem.squashfs /`
* Try: `losetup -r /dev/loop2 /filesystem.squashfs`
* Result: `loop2: detected capacity change from 0 to 1460312` -> PASS
It appears that the loopback device cannot be used any more with the mount /run/live/medium (which is on /dev/sr0). 

I've verified: the md5sum of the squashfs file is OK.

The newer kernel is not in trixie yet.

With kind regards,
Roland Clobus
PS: With debian-boot in CC, since the newest kernel might be a candidate for trixie.
