The other issue concerning runtime PM is that as soon as I set a non-zero to
the autosuspend_delay_ms I get some garbage characters and eventually the

[root at arago /]# cat .../omap_uart.0/power/autosuspend_delay_ms
-1
[root at arago /]# echo 3000 > ?KW???+???+wU.???,z,??.??osuspend_delay??????...

Its enabled.

I checked on Beagle-xm with latest LO master I don't see that issue.
