            Bug ID: 73194
          Assignee: systemd-bugs at lists.freedesktop.org
           Summary: journal: Missing byte order conversions break chain
                    cache on big endian
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: george.mccollister at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

Running 'journalctl -f' on big endian machines results in only 1 line of
history rather than default of 10. gdb shows that the begin argument is not
being converted to host byte order prior to being passed to chain_cache_put.
