 |
|
Hi,
I've managed to buy a discarded server from my employer, so I have a pretty big iron at home.
Unfortunately big iron means noise and power consumption too, so I had a look into power management and hibernation in general.
Most of the HowTos seem to cover these topics for Notebooks so I do not have much to catch on.
I use Kernel 4.5.2, ACPI and hibernation seems to be enabled
| Code: |
# cat /sys/power/state
freeze standby
|
After some tweaking, best result so far is that when I do a "pm-suspend", machine stops responding 
But other than that all fans still run, all non-SSD disks still spin...
I can wake it up again by pressing a key on the attached keyboard (but not via IPMI keyboard)
The whole process of suspend/wakeup looks like that:

Any ideas what I could do to get the machine into "true" suspend? I really do not need any fancy stuff suspend-to-ram with disks and fans not spinning would be sufficient.
