How does an MR get reviewed? +This is not uncommon and may be due to a config difference between RHEL and Fedora. One key difference between the two kernels is that Fedora has enabled CONFIG_BTRFS where ELN/RHEL has not, and as a result ELN/RHEL kernels will not mount Fedora BTRFS filesystems. If you are booting the ELN/RHEL kernel config on Fedora you must change these configuration values in the .config: + +.. code-block:: sh + + CONFIG_BTRFS=y + CONFIG_BTRFS_FS_POSIX_ACL=y + +If that change doesn't resolve the boot failure, users should attempt to "flip" configs to determine the difference between the two flavors before reporting bugs.
