Describe the bug

After flashing KernelSU (LKM) and rebooting the device, the cellular signal becomes highly unstable. I frequently encounter a "No Service" status or extremely weak signal strength immediately after a reboot. After some time, the connection eventually becomes stable, but the issue can also trigger randomly during normal usage.

To Reproduce

1. Flash KernelSU (LKM) on a Pixel 8a (currently using dual eSIM configuration).

2. Reboot the device.

3. Observe the signal status: it will show "No Service" or very low bars for several minutes.

4. Sometimes, the signal drops randomly while the device is in use.

are you certainly sure that it's caused by KernelSU? and isn't an effect from modules installed or any app with granted super-user?
