Where does F33 keep the messages from the last system crash?

If they were captured, I think one of the places they would be is the journal. journalctl -r will read the journal from the end towards the beginning. You will have to bypass the session that is the reboot you are reading from.

"journalct -b -1 -r" will start with the last messages before you rebooted and go backwards from there.

Thanks. This is what I got: Jan 06 15:32:47 localhost.localdomain kernel: SELinux: Permission watch in class filesystem not defined in policy. -- Reboot -- Jan 06 15:10:29 fedora firefox.desktop[611691]: ###!!! [Parent][DispatchAsyncMessage] Error: PMessagePort::Msg_PostMessages Processing error: message was> Jan 06 15:10:29 fedora firefox.desktop[611691]: IPDL protocol error: Handler returned error code! -- Reboot -- Jan 06 09:32:37 localhost.localdomain systemd-journald[176]: Journal stopped
As far as I could tell, the system was running fine at 15:37 and for a bit after that. It had been running since yesterday and my firefox windows were up. Shortly after 15:37, I plugged in a USB cable with no device attached. I heard what I took to be the fan being real busy and unplugged the cable. I then tried to move the mouse so that I could close firefox. Could not even see the mouse. Shortly thereafter, "no signal" on the monitor and rebooting started.
So far as I know, nothing interesting happened at 9:32:37 today. The available evidence, my firefox windows, suggest that there was no reboot at that time.
What happened? In the alternative, how do I find out what happened?
I've had almost the same thing happen before. I'd plug in a USB cable, possibly with a cell phone attached, though not this time, the fan would speed up and the mouse would freeze. Complete lock up. Could not even switch virtual windows.
Any ideas?
well, if you plug in a usb device and that happens that indicates the hardware completely reset.
If it was just a kernel crash then the machine would have stayed hung until you reset/power cycled it.
It would have to be it crashed because of the usb device being plugged in, and it would have to be a hw issue since it immediately rebooted.
So something about either the device you plugged in or the usb bus you connected to. If this was an add-in card make sure its extra power connection is plugged in.
I do have a couple of pci-e usb cards that do not work right on a really old motherboard I have and will (if used with say a usb camera) immediately reset the machine the instant a program opens the camera.

To me, the weird thing was that there was no device, just the cable.

On this machine, a crash seems to be always followed by an automatic reboot. Not good. Even if it reboots from the internal drive, it come up with my ethernet connection available. Sometime I have connected a USB drive that still has an old system on it. I've never gotten around to telling it no USB boot.
