Bug description:
  Issue spotted on Impish AWS 5.13.0-1008.9 with node a1.metal only
  (ARM64 bare metal).

  Test failed with:
      TFAIL  :  rtc01.c:73: RTC_RD_TIME ioctl failed: errno=EIO(5): Input/output error

  Note that this test has passed with 5.13.0-1007.8 with LTP head SHA1
  2ac54d426 and 5.13.0-1006.7 + LTP head SHA1 9ce71152b in previous
  cycles.  However, I tried to reproduce this manually and it's failing
  with 5.13.0-1005 / 1007 and 1008 with the same LTP head (2ac54d426 or
  9ce71152b). I am not sure why it has passed in the past.
