I was awaiting word on that. >> >> hm, does bot@xxxxxxxxxxxx actually read emails? Let's try info@ as well.. bot@xxxxxxxxxxxx is not person, it's a send-only account for automated reports. So no, it doesn't read emails. I guess the tricky point here is that the authors of the commits found by bisections may not always have the hardware needed to reproduce the problem. So it needs to be dealt with on a case-by-case basis: sometimes they do have the hardware, sometimes someone else on the list or on CC does, and sometimes it's better for the people who have access to the test lab which ran the KernelCI test to deal with it. This case seems to fall into the last category. As I have access to the Collabora lab, I can do some quick checks to confirm whether the proposed patch does fix the issue. I hadn't realised that someone was waiting for this to happen, especially as the BeagleBone Black is a very common platform. Sorry about that, I'll take a look today. It may be a nice feature to be able to give access to the KernelCI test infrastructure to anyone who wants to debug an issue reported by KernelCI or verify a fix, so they won't need to have the hardware locally. Something to think about for the future. >> Is it possible to determine whether this regression is still present in >> current linux-next? I'll try to re-apply the patch that caused the issue, then see if the suggested change fixes it. As far as the current linux-next master branch is concerned, KernelCI boot tests are passing fine on that platform. Guillaume
