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?
