We are ignoring too many bug reports and don't have a formal bug
triage process, so unsurprisingly lots get
lost/unnoticed/unconnected/etc.
I've looked at the pile of corrupted reports:
https://syzkaller.appspot.com/bug?id=d5bc3e0c66d200d72216ab343a67c4327e4a3452
and spotted these 4 that look relevant:
