panic: modified loader.conf and SD card plugged in

I'm experiencing a very similar issue with my T440p, but without any docks.
When I try to boot an unmodified FreeBSD-13.0-RELEASE-amd64-mini-memstick.img
while the laptop's SD card slot is empty, I get the same kernel panic as
https://bugs.freebsd.org/bugzilla/attachment.cgi?id=223437. (Some of the
addresses are different; I can upload an image if necessary.) If I plug an SD
card into the slot before booting, the unmodified image boots fine.

I also tried a modified image with the lines

dev.rtsx.0.inversion=1
rtsx_load="YES"

added to loader.conf. With no SD card it boots successfully, but on the first
installation screen these lines slowly overwrite the interface:

rtsx0: Controller timeout for CMD8
rtsx0: Controller timeout for CMD8
rtsx0: Controller timeout for CMD8
rtsx0: Controller timeout for CMD55
rtsx0: Controller timeout for CMD55
rtsx0: Controller timeout for CMD55
rtsx0: Controller timeout for CMD55
rtsx0: Controller timeout for CMD1
rtsx0: Controller timeout for CMD1
rtsx0: Controller timeout for CMD1
rtsx0: Controller timeout for CMD1
mmc0: No compatible cards found on bus
iwm0: hw rev 0x140, fw ver 17.352738, address 7c:7a:91:c2:9b:56

I cannot perform any interface actions until the last line prints. When I boot
the modified image with an SD card plugged in beforehand, I get the attached
kernel panic.
