Overview:

Updating to a kernel that is >=6.9.x leads to the system being unable to
correctly read and assemble MDADM RAID devices, works fine with older
Tumbleweed kernels (e.g. 6.8.x kernels)

Steps to Reproduce:

1. Create a RAID 1 device with MDADM, with LVM volumes within, formatted with
BTRFS
2. Update to newer kernel version in TW, higher than 6.9

Actual Results:

System fails to correctly assemble MD devices, only some LVs are visible and
mountable on 1 disk. Secondary disk does not appear to be part of the MD array,
and LVs do not appear. 

OR 

Replugging the devices cause other LVs that could not be read during boot time
to appear, but are not mountable and readable. Original readable LVs are not
visible after replugging.

Expected Results:

All created MD devices and LVs should be assembled and mountable correctly. 

Build Date & Hardware:

I am unsure about the specific build, but I have tried 2 6.8 kernels (6.8.3,
6.8.5) by rolling back the system, and it functions correctly. Updating to a
snapshot with a kernel >6.9 causes the issue. Updating to a newer snapshot with
the kernel-default package appears to not trigger the issue. 

Additional Builds and Platforms: Whether or not the bug takes place on other
platforms (or browsers, if applicable).

Occurs on an installation with MicroOS, and Slowroll with kernel >6.9, have not
tested other distributions.

Additional Information:

System is a X1 Carbon with 2x Seagate Ironwolf drives attached via a USB
enclosure. Functioned for 2 years, and tested with new, identical USB
enclosures and other laptops to confirm the issue, which is replicated
identically. 

When the devices can be mounted correctly with older kernels, SMART data and
BTRFS scrubbing did not identify any issues.
