this looks to me as if for whatever reason the kernel still wants to use ttySAC0
as serial console, rather than as non-console port for the GSM modem.

Due to UART shortage, FIC made the early design choice to multiplex the UART0
between GSM modem and console.

The gsm power control kernel driver unregisters the port from the kernel console
switch and then uses it as GSM uart.  Now if that fails, and the kernel still
wants to use it as console, we could expect some problems.

Now maybe this unregistration fails for whatever reason.

I suggest booting without the "console=ttySAC0,115200" part in the bootcmd. 
Then the serial port will never be used as console port in the first place.
