           Product: File System
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3

          Assignee: filesystem_xfs@xxxxxxxxxxxxxxxxxxxxxx
          Reporter: dagmcr@xxxxxxxxx
        Regression: No

While doing fstests baseline testing on v6.6-rc5 with kdevops [0] we found a
failure for xfs/538 test. 

[0] https://github.com/linux-kdevops

This fails on the following test sections as defined by kdevops [1]:

  * xfs_crc_logdev_rtdev: failure rate ~1/17
  * xfs_crc_rtdev_extsize_64k: failure rate ~1/3
