Thank you, but that board seems to still have problems:

https://lava.ciplatform.org/scheduler/job/458108


expect-shell-connection: Wait for prompt ['root@ebsy-isar:~#'] (timeout 00:10:00)
Waiting using forced prompt support (timeout 00:05:00)
end: 2.3.5 expect-shell-connection (duration 00:00:00) [common]

(Of course, I can't rule out kernel problem at the moment, but failing
at setting environment variable would be strange.)

Best regards,
