Dmesg from 3.10.17
After upgrading from 3.10.17 to 4.14+ ( but I suspect it started on 4+ ) my
machine has a strange behavior hibernating and suspending.
When I start the hibernation everything seems fine, but as soon as the machine
goes off ( hibernating ) she starts again.
I can at this moment power off her by long pushing the power button ( without
trouble as I have elilo that wait for a key press before booting ).
When I push the button to resume her the resume goes without problem but after
few seconds she start a new hibernation cycle ( that does the same thing as
before ).
After this new ( unwanted ) hibernation if I power on her again the resume
works without problem and there is not a new hibernation cycle.
I can then use the machine without problems, but when I ask for hibernation
everything starts again as described ( restart after hibernation and two resume
needed to use again ).
I can avoid this second resume cycle by modifying the pm-action script checking
how long is passed from the previous hibernation cycle, but I cannot do nothing
for the "restart again" phase.
I have tried on 4.4.14, 4.14.31, 4.16.0 and it behaves in the same way.
I can't actually test on 3.x as it don't compile on gcc 5
The same happens when I suspend ( two cycles of everything )
I will attach the relevant part of dmesg from the three kernel.
Please apologize for my ugly description but I'm not native english so please
feel free to ask for more detail.
