Red Hat Bugzilla – Bug 472589
pm-hibernate does nothing if serial console is enabled
Last modified: 2014-06-25 16:48:03 EDT
Description of problem:
Configured serial console by putting "console=ttyS0,115200" into the boot line. pm-hibernate then runs through hibernate and thaw hooks without attempting to hibernate. It appears that:
dbus-send --system --print-reply \
does not work. No idea why.
Version-Release number of selected component (if applicable):
Is dbus running properly on the system?
# ps -fe | grep dbus
dbus 2132 1 0 Dec18 ? 00:00:00 dbus-daemon --system
If I run the dbus-send command by hand in my ssh session, it goes into hibernate.
Is this an authorization issue? dbus need to be running on the console, but it isn't with the serial console enabled?

Does this also happen with pm-suspend in your case?
Error: kernel cannot suspend to ram.

It turns out running PM_DEBUG=true pm-suspend provides an interesting log file. I'm a little dead at the moment but I'll try taking a closer look at it tomorrow.
