Aaah, hmmm.
I'm trying to trace a problem with resume. Once in every 5-10 times resume
fails with dead display even though most times it resumes perfectly. So I
was trying the suggestion in Documentation/power/s2ram.txt and am doing
'echo 1 > /sys/power/pm_trace' before suspending.
Just now I find [1] which mentions that the trace info is saved in the
RTC, which I guess could well explain the jump. If that's what behind
this, wouldn't it make sense to mention that fact in s2ram.txt?
But I would not expect the RTC to get changed when the resume is
successful. Or does it just get updated with every resume step without a
reset to the pre-trace value on completion?
