Hi,

I build and tried this latest on Beagleboard (C2). Booting from MMC
using ramdisk image. I changed the LL console to the 3rd UART.

The issue I have is that after the system boots up it works for as
long as I keep actively using it but if I leave it idle for a short
time (~5s) it stops responding. I have tried waking it up using both
UART and "USER" button on the board. This is with the default PM
configuration.

If I put the board into suspend (retention) it wakes up without any issues.

Also, if I enable "/debug/pm_debug/sleep_while_idle" board wakes up
without issues. Well the first couple characers on the console seem to
go missing but I guess without CTS/RTS that is expected?

Any pointers would be appreciated.

 - Juha
