I updated the trac ticket with most of what was requested.

When going to 12.1.0 I held down the four buttons above the power switch
while booting. When going to 13.1.0 I used fs-update. I was going by the
instructions on the wiki for doing the updates.

I also didn't have two sources of power when I did the fs-update to 13.1.0,
so maybe that's why the open firmware is still at Q4D17.

I don't know, but probably whatever you were shipping with the devices
a few weeks ago. Mine shipped shortly before 12.1.0 was released.

I can reproduce the issue on Q4D17.

It is still Q4D17.

I can't refer to u: successfully if I don't plug in the drive after booting.

I haven't got Q4D21 yet, so I can't do these tests just yet.

There were differences for the p2 command under Q4D17 depending on whether
the drive was plugged in before or after boot.

In my case it's a flash drive. (I reformtted it to ext4.)
