This is a modified version of a message that I sent to testers, but didn't
arrive because it got stuck in the mail queue. (More about that in a
separate message.) It's still in the queue, so disregard it if it happens
to show up.
I hadn't realized that in 9.4, things showed up as ? instead of
"Permission denied," so that part isn't so surprising. However, since I
had just gotten tokens a moment before, the directory entries shouldn't
have shown up with ? anyway.
Here's the /var/log/messages for the kernel oops that happened just after
did the ls:
