Hi Krzysztof. Thanks for your  prompt response!

However, I'm really careful to check sybot and lkml to make sure that
my report is not duplicated. Can you provide specific information on
with syzbot dashboard or maybe this one is duplicated with another bug
that I do not notice?

BTW, I'm doing some research on reproducing non-reproduction bugs on
syzbot. This one is another not on the dashboard but when I reproduced
and triggered it on the last net tree, I think it is still necessary
to report for helping fix it.

Merry Christmas~~~
