Thank you so much for your time you all.

New microSD arrived today. It is a SanDisk Ultra, see this on the Raspberry
pi 3B+:

```
root@generic:~ # dmesg | grep -i mmc
mmc0: <MMC/SD bus> on sdhci_bcm0
mmcsd0: 32GB <SDHC SD32G 8.5 SN A0169EA9 MFG 04/2021 by 3 SD> at mmc0
50.0MHz/4bit/65535-block
```

50 MHz !! What a relief.

Other OS like RaspiOS and NetBSD runs well on the other cards, not sure
why. I still don't understand why sandisk is the only brand that works for
FreeBSD apparently.

I'm willing to give more information if needed or even to open a ticket in
bugzilla if you find it useful.

Have a great weekend !!

PS: I've also bought the usb ttl cable if I can give any more information
using the other card via serial console.
