Ah,  I see.
You can now see the current status on dashboard:
https://syzkaller.appspot.com/bug?id=d4ac7bfeafac8a3d6d06123e078462ac765415e7
Yes, it still happens.

syzbot has already reported another incarnation of this bug, you can
see the link to dashboard in the email:
https://syzkaller.appspot.com/bug?extid=b8d5eb964e412cfd2678
and it contains a link to the first version with reproducer.

syzbot does not test rdma-next.

But can you reproduce it on upstream tree where syzbot hits it? Just
to make sure, you have ODEBUG enabled, right?
