`dash` and `ash` are very similar, this is unlikely to be the cause.

I am pretty certain that tbot is waiting for a password prompt.  Can you
check that you have set `password = None` in your board linux config?

Skip does not really make sense in tbot's design, where other testcases
might depend on one testcase's return value.  If you want to skip, do it
like `selftest_board_linux`:
