Re: Need help on Suspend on RAM

[Francesco VIRLINZI <francesco.virlinzi@xxxxxx>]

Hi all
I think I find a fix (?)
In the file:
kernel/time/timekeeping.c
I'm removing the functions:
 - timekeeping_suspend and
 - timekeeping_resume
I forgot to say that I have no real ClockSource (this means that in 
suspend also the clocksource is suspended...)

Could it be a fix or there is an other solution?
Regards
 Francesco
