Additionally, I'd like to provide some context regarding the current 
behavior.

While the driver works correctly on my hardware, other users have 
reported encountering I/O errors (for reference, see this report: 
https://forum.archlinuxcn.org/t/topic/14050/8 
<https://forum.archlinuxcn.org/t/topic/14050/8>).

These are the information the user provided:
