Jun  8 16:52:32 laptop kernel: mmc0: No compatible cards found on bus

and keyboard stop working for a ~30 sec
Now, plug card back:

Jun  8 16:53:55 laptop kernel: rtsx0: Interrupt card inserted/removed
Jun  8 16:53:55 laptop kernel: rtsx0: Card absent
Jun  8 16:53:55 laptop kernel: rtsx0: No request running
Jun  8 16:53:55 laptop kernel: mmc0: detached

Looks like attaching/detaching card swapped + I don't have any mmc* devices in
both cases

it is FreeBSD 13.0-CURRENT #1 r356767M, Lenovo t470p
