[Bug 2137257] Re: Add support for Medion SPRCHRGD 14 S1 Laptop - Qualcomm Snapdragon X Elite X1E-78-100 - 32GB RAM

[James Addison]

Since my last comment, I've also tested the Ubuntu Concept 20260229 (?)
image.  That did display a graphical splashscreen after GRUB menu entry
selection, and did boot as far as successfully launching many systemd
services/checks (lots of green 'OK' status line messages).  However, the
device rebooted suddenly while still in text-mode display -- it neither
reached a graphical desktop nor offered a login challenge on the
console.

The last few lines on the console output before the reboot, as captured
from a slow-motion video recording of the laptop screen, seem to
contain:

snd-x1e80100 sound: probe with driver snd/x1e80100 failed with error -22
qcom_geni_serial e90000,serial: failed to read firmware-mmap property: -22
qcom_geni_serial e90000,serial: UART firmware load failed ret: -22

Some of the video recording is a little out-of-focus / blurry, so there
may be a few typos in that transcription of the output.

Title:
  Add support for Medion SPRCHRGD 14 S1 Laptop - Qualcomm Snapdragon X
  Elite X1E-78-100 - 32GB RAM

Status in ubuntu-concept:
  New

Bug description:
  I'm still in the situation where only `Try or Install Lenovo Ideapad
  Slim 5x` works but the actual device `Medion SPRCHRGD 14 S1` does not
  work. Note, this is the `Qualcomm Snapdragon X Elite X1E-78-100` not
  the plus version.

  I've had to add a statement in Grub to select a different device tree
  for it to boot. My `/boot/grub/grub.cfg` contains the first version
  because that seems to work whilst the second one causes it to reboot:

  ```
  devicetree /dtbs/x1p42100-lenovo-ideapad-slim5x.dtb
  ```

  
  This does NOT work:

  ```
  devicetree /dtbs/x1e80100-medion-sprchrgd-14-s1.dtb
  ```

  I've attached the `.dtb` that does not work that should work.
