Have you try

in /boot/loader.conf with the device enabled on BIOS?
Not yet :-) I'll try.
If not yet, it would be worth trying.
In rtsx(4) manpage,
〓 RTS522A on Lenovo P50s and Lenovo T470p, card detection and read-only
switch are reversed. This is sovled by adding in loader.conf(5):
dev.rtsx.0.inversion=1
If it works for you, possibly no one had tested on T540p yet.
And there can be much, much more PCs/chips which need it, but no one has
tested yet.
My rtsx driver on ThinkPad P52 works fine without it, but IIRC,
paniced with it (I did it just a test purpose when it landed).
And one more.
If you insert write-protected card and then mount it as writable,
it SHOULD certainly crash the system.
It's not a rtsx driver issue, but promised to happen.
I've encountered the problem on USB card readers, too.
My slot is empty, no card, no adapters, no plastic pseudo-card, nothing.
