Hi, two apparently significant patches for omap-serial have arrived in 4.11.2:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm... https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...
I have not seen these problems (due to incomplete test coverage) but potentially this can fix issues with the serial console, Bluetooth and GPS in combination with suspend.
Therefore I have upgraded our letux "latest" kernel to 4.11.2 and rebuilt the binaries:

As usual there is also an lpae configured version (OMAP5 only):
