sorr that we don't have enough knowledge to connect the issue with code change.
we just rebuild kernels for this commit and its parent, confirmed they are still
built with the config we shared in the link in our original report, then rerun
the tests, found still clean on parent, but reproduciable on this commit.
this is just FYI what we observed in our tests. if you want to look at this
further and you have a debug patch, we could do more tests with it. Thanks
