the hardware does not seem to be relevant. Do you have anything calling
"racadm lclog" on fairly regular basis? it creates and destroys a usb

Title:
  cat /sys/fs/cgroup/blkio/blkio.time_recursive  took 1second to
  complete

Status in linux-meta package in Ubuntu:
  Confirmed

Bug description:
  Issue:

  ```console
  # time cat /sys/fs/cgroup/blkio/blkio.time_recursive
  8:16 354721435

  real    0m1.297s
  user    0m0.000s
  sys     0m1.297s
  ```

  As could be seen from above result, cat blkio took about 1 second to complete 
which
  is much longer than a normal case.

  Kernel Version:

  Linux compute08 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02
  UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
