pty04 in ubuntu_ltp failed

[Sean Feole]

series: Bionic
kernel: 4.15.0-125.128 - generic
test: ubuntu_ltp -- pty04,
host: nvidia.dgx2

This appears to be a regression we have not seen this in the past, most likely needs to be run manually to get more information. Could be a race condition, not to sure.
