WiFi on the Xiaomi Elish device functions correctly with kernel version 6.12.4. However, after upgrading to kernel 6.12.13 via apt, the NetworkManager reports that the device is "not ready," and the WiFi fails to initialize. I have also tried reinstalling the system by flashing the kernel and rootfs downloaded from [Armbian for Xiaomi Pad 5 Pro](https://www.armbian.com/xiaomi-pad-5-pro/), but the issue persists.
