HiSince you backported 41044b41ad2c8c8165a42ec6e9a4096826dcf153 to 6.8.3 and higher, the kernel crashes hard on boot if BTRFS's sanity checks have been enabled (CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y).
Please backport b2136cc288fce2f24a92f3d656531b2d50ebec5a to the stable/mainline series fix this issue.
Best regards Mihai Moldovan
