Yeah, that seems pretty old. I am confident that we did not see this issue with 4.4 or even 4.19. […]
Although unlikely, it could also be that this bug has been un-noticeable for a while. On an unpatched soraka it fails around 1/10 reboots. And I know Tomasz could not even replicate it in some other boards...
We can try to bisect when this started to fail... but it could be quite a long job. Also I am not sure that all the path from 4.4 to 5.4 is bisectable.
