micropython 1.15 esp32 reboot at SD deinit

[emard]

After unmounting SD card I need to release it's pins (to input or hi-z) for this I want to deinit SD card and set pins to input, but at deinit ESP32 reboots. esp32spiram-idf3-20210202-v1.14.bin doesn't reboot, but idf4 versions reboot.

>>> import os
>>> from machine import SDCard, Pin
>>> sd = SDCard(slot=3)
>>> os.mount(sd,"/sd")
>>> os.listdir("/sd")

Great, it doesn't crash after umount and deinit, but it won't mounting it again?
