We will try to root cause the issue and provide a fix, if possible.

Since 5.4.206 is a longterm release kernel, we were under the
impression that the community is still accepting fixes and patches for
the same. I understand that adding another bug to the already pending
queue of syzbot reported issues is not going to help the developers
much. Therefore, we will definitely try our best to analyze the issue
and provide a fix in the coming days. Can you please confirm that it
is worth the effort for the longterm release kernels?
