Hi all,
we are using the lava system for test of several i.mx6 boards with yocto based linux images. Sometimes the test cases failed with following error message: "Test error: Unable to handle the test shell signal correctly: _on_sync() takes exactly 2 arguments (16 given)"
This is the problem of kernel message interlacing with stdout.

All the advice is available on that page.
A closer look into the logfile shows, that the Message "<LAVA_SIGNAL_TESTCASE ... >" seems to be interrupted by output of kernel messages.
# example from logfile start#

Is there someone with semilar observations and a solution for this problem?
