AM335x Run-time PM, UART run-time resume problem

Hello,

Processor AM335x, linux-3.2.0-psp04.06.00.11

I activated run time pm for serial interface including console (uart0-uart5).

Suspend timeout 7 Sec. Console suspends after inactivity timeout.

I have  a problem to resume uart from keypad activity.

Any ideas to resolve it?

Thanks in advance,

Yuri.
