If anyone has any objections, please let me know. ------------------ From: Edson Juliano Drosdeck commit 50c78f398e92fafa1cbba3469c95fe04b2e4206d upstream. Disable command queuing on Intel GLK-based Positivo models. Without this quirk, CQE (Command Queuing Engine) causes instability or I/O errors during operation. Disabling it ensures stable operation on affected devices.
