Thanks for running the test.


Thanks for staying with me.


I am not very familiar with the code, but I think we shouldn't hit that
WARN_ON_ONCE. Could you please try with the follow patch to see
which section caused this issue?

Thanks,
Song

I put that as -patch3 on top of 6.4-rc3, the result is on [1].

I this time put the whole console messages there, just in case some of
the earlier messages could be of any help. To jump to the actual oopses,
search for "Loading, please wait...".
