Accessing SDCard/mmc crashes system

Hello!

On my Arch system (Notebook Lenovo Miix 320, installed on internal 64Gb eMMC mmcblk0) accessing the micro SD card in the internal card slot freezes the system (i.e., black screen, cannot switch tty, reboot necessary).

lsblk shows the card as:

 mmcblk2 

and its partition (vfat):

 mmcblk2p1 

By accessing I mean using any of (as root):

 fdisk /dev/mmcblk2 

 parted /dev/mmcblk2 

 mkdir testmnt && mount /dev/mmcblk2p1 testmnt/ 

 mkfs.ext4 /dev/mmcblk2p1 

 blkid 

When booting without the card inserted and after inserting the card

 dmesg | tail 

returns:

 mmc2: new ultra high speed SDR104 SDHC card at address 59b4 
 mmcblk2: mmc2:59b4 EB1QL 29.8 GiB
  mmcblk2: p1 

This was tested with a 32GB class 10 SDHC (Samsung Evo Plus) card. Other class 10 cards (32 / 64 / 128 / 200GB, different manufacturers) result in the same freeze. All of them work with Windows 10 on the same device.

Does anyone have an idea how to fix that?
Thanks!
