Description

Sometimes the serial output gets lost.

This doesn't happen constantly.

Example:

COMMAND ; echo 123123-$?- > /dev/ttyS0

and the test will fail with:

# wait_serial expected: qr/(?^:123123-\d+-)/

# Result:

even when the COMMAND was executed without any issues. There's no entry in the serial0.txt file.

For now only i noticed in x86_64.

This happened in the test: https://openqa.suse.de/tests/1114687#step/piglit/14

It happened again on the same piglit test: https://openqa.suse.de/tests/1116829#

This made me realized that it might be related with the VIRTIO console.
