It looks to be extremely rare. Aliases are extremely rare, front merges
are rare. And you need both to happen with the details you outlined. But
it's a large user base, and we've had 3-4 reports on this in the past
months. So it obviously does happen. I could not make it trigger without
doctoring the unplug code when I used aio.
Well, not that rare on this particular machine (I had a case where I could reproduce it in less than
an hour of normal use previously on this box), and I've had it occur a number of times on my
servers, I just never reported it before as I never took the time to set up a serial console and
capture the oops.
Here's a fix for it, confirmed.
Shall I leave the other debugging in, apply this and run it for a few hard days?
