dmesg (journalctl -k -b -1) & lspci -kkv

My 6.3.8 kernel says Oops, NULL pointer dereference, address: 0000000000000054,
when I successfully unlock my Xorg session that is locked by xsecurelock
(https://github.com/google/xsecurelock) when my screen(s) have not yet turned
back on.

* Lock the screen with `xsecurelock(1)`
* Wait until the monitors go to sleep (I unplug my mouse and keyboard thanks to
a little USB KVM)
* Quickly type my password and <enter> to unlock my session before the screens
turn back on

Unexpected: machine ~freeze (X11 not responsive, machine won't reboot properly
(`reboot`), but I can initiate a SSH session and `echo b > /proc/sysrq-target`)

The attached dmesg was obtained with `drm=debug=4` in cmdline.

`lspci -kkv` also attached.

Hardware list: B550 Phantom Gaming-ITX, 5800X, RX6950XT reference design card.
