AFAIU there two bugs here and you've fixed the first one, but the second one gets triggered. I think the second one got reported separately here: https://syzkaller.appspot.com/bug?extid=5b9bba68c833c84a1135 That one has a reproducer with a single dummy-hcd, so you can try running your debugging patch against that report. I'll see if I can run it manually in the meantime.
