[tbot] How to debug acquire_linux

I have a board that cannot be got in linux. It looks like that
tbot.acquire_linux() hangs forever (can I set a tiimeout ?)

I ran a testcase that works fine for another board - I guess that the
issue is due to the fact that this board has a lot of output in part
caused by systemd and in part due to kernel messages that are printed to
the console. When I start the testcase, tbot remains in <board>-linux. I
can understand that board is up and works because software activates
some relays, but it is not recognized by tbot.

The weird thing is that "interactive_linux" works. How can I debug this
? Or do we have to block kernel messages to the console via kernel
parameter ?
