Ah, and there it triggered again. I again hadn't touched the laptop, but
I tried to start a 'konsole' and while it was showing the bouncing icon
it triggered.
Same backtrace, but I did a more extensive strace, showing that it
typically stays in the ioctl for about 0.019 seconds before exiting
(>50hz).
$ sudo strace -Ttttip 9029
Process 9029 attached - interrupt to quit
