Partial boot after installing Manjaro on emmc

[regivanx]

After booting from the SD card, linux is apparently no longer able to detect it:



Note that the sd card is encrypted by cryptsetup.

With an unencrypted sd card, linux does not give access to the emergency shell.

From the emergency shell, it is possible to mount a usb key in /new_root and start an operating system in very degraded mode:

• already, during the emergency shell, linux only detects the usb key if it is plugged in on the left.
  
• the computer goes to sleep several times during startup.
  
• no network interface wlan0.
  
• only detects the usb key on the left, the one that contains the operating system. The usb on the right does not work, neither for a usb key nor for a mouse.
  
• does not detect the sd card.
