Hi, there. I wonder if anybody else is seeing the same problem with el7:
The symptoms are: no ping, dead video, dead keyboard. After power cycle,
syslog shows that the system has attempted to go into sleep or suspend
or whatever they call it.
This is very strange, usualy a system will go into suspend mode when you
close the laptop lid, but these are not laptops. They are normal desktop
machines (and at least in one case, there is no local user to blame for
pressing the "sleep" button).
So what's in the syslog:
- normal activity (systemd spam)
- network manager reports "sleep requested"
- some kind of nm_dispatcher activity
- systemd reaches sleep and suspend targets.
- continues spewing sundry messages, never recovers (never goes into
actual sleep).
The machine is effectively dead after network manager put the network
interfaces to sleep.
Can the machine be made to respond to wake-on-lan ?
If so, setting that up *might* reduce the pain when this happens again ...
What does hostnamectl report for chassis type? I haven't had a sleep
issue, but I do find desktop boards get set to laptop incorrectly. I
tend to force this to server in my kickstarts.
