Some more details to reproduce:
With this repo, run: lavacli -i lava-docker jobs submit example/lava.job

Now, in Zephyr tree (master 1f18b9c7e25c7277), build tests/subsys/logging/log_list for BOARD=frdm_k64f. Replace test-images/frdm_k64f/logging.log_list/zephyr.bin with the new binary from the built test. And run lavacli -i lava-docker jobs submit example/lava.job
again:

So, we'll need to update test patterns, but bigger question is what's up with zephyr-upstream test in CI - based on SQUAD notifications, I didn't see any catastrophic test regressions, so would need to look there too.
Ok, so here's this specific test in production CI: https://validation.linaro.org/scheduler/job/2127422 . Here it looks ok, so apparently we use different patterns there (Vincent fixed some mis-matching a couple of months ago).
But before I arrived at that, I saw this: https://validation.linaro.org/scheduler/job/2127812 . Here it's clearly not right, as testcase matching ends prematurely. But on closer look, there's some problem with output, looks like older test's output is still in the input buffer, or 2 outputs are interspersed, or something. And that's on frdm_kw41z which is known to be not very stable. And well, I have suspicion that LAVA lab USB/UART routing infra is susceptible to glitches like that, but didn't have a chance to concentrate on it and dig to the bottom.
All in all, I'll work on both updating our sample and making it consistent with production patterns.
Fixed by 2 PRs above.
It appears that zephyr test harness has evolved 'recently'.
It used to be something like:
Now, same test throws:
The string
starting test - test_log_list
disappeared. Issue is that it was used as pattern for test start detection:Waiting for start message: (tc_start\(\)|starting .*test|BOOTING ZEPHYR OS)
As a consequence, tests run with a recent Zephyr are all failing.
