Hi,
I was using a USB->Serial converter on my x240t:
uplcom0 at uhub3 port 1 "Prolific Technology PL2303 Serial" rev 1.10/2.02 addr3
I got the following panic (typed by hand, so beware of typos):
---8<---

The crash occurred shortly after I had unplugged and re-plugged the
USB->serial adapter: I had a getty on ttyU0 which was locking the line,
and I wanted to use it for something else (I've since removed the line
in /etc/ttys).
I guess the kernel doesn't like this device to disappear.
Cheers. Full dmesg for x240t follows:
