I sent another mail yesterday which is now at https://lore.kernel.org/lkml/CADVatmOOzCxAgLhCu1tTz=44sgRDXds5-oMZ3V0w4f5kLCLKrw@mail.gmail.com/ I will just pase that here for you.
Last night's test on 66f4beaa6c1d worked fine. So I guess this has now been fixed.
I have not done a bisect to see what has fixed it, but looking at the log I think it will be that NULL pointer fix.
-- Regards Sudip
