            Bug ID: 93031
           Summary: root becomes read-only at boot due to
                    journal_async_commit in /etc/fstab
           Product: File System
           Version: 2.5
    Kernel Version: 3.18.5
          Hardware: x86-64
                OS: Linux
              Tree: Fedora
            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx
          Reporter: mtall.qld@xxxxxxxxx
        Regression: No

Booting kernel 3.18.5 with the journal_async_commit option for / in /etc/fstab
causes the root file system to be read-only. kernel 3.18.3 also has this
problem.

entry in /etc/fstab:
UUID=...  / ext4  defaults,nodiratime,noatime,journal_async_commit 1 1

Relevant log from dmesg:
EXT4-fs (sdb1): changing journal_checksum during remount not supported

Adding journal_checksum to /etc/fstab doesn't help.  Trying to manually remount
root to enable or disable journal_async_commit also doesn't work.

kernel 3.17.x works without problems.
