Description Lenny Szubowicz 2015-12-22 10:46:12 EST
Description of problem:

RHEL 6.8 BZ 910715 against the kernel complains that pm-suspend-hybrid does not work in RHEL 6. 

In response to that BZ the kernel support via sysfs /sys/power/disk and /sys/power/state has been added.

However, even with the kernel support in place, the pm-suspend-hybrid command does not notice or utilize this support without a patch to the pm-functions shell script.

The relevant pm-utils patch from rhel-7.x is pm-utils-1.4.1-add-in-kernel-suspend-to-both.patch

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. pm-suspend-hybrid

Actual results:

Using a test kernel with support for suspend hybrid.

[root@uefi09 ~]# uname -a
Linux uefi09.desklab.eng.bos.redhat.com 2.6.32-593.el6.bz0910715.lss01.x86_64 #1 SMP Mon Dec 21 13:15:36 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

[root@uefi09 ~]# cat /sys/power/disk
[platform] test testproc shutdown reboot suspend 

Attempt to invoke pm-suspend-hybrid does nothing except return an error

[root@uefi09 ~]# pm-suspend-hybrid
[root@uefi09 ~]# echo $?

Expected results:

echo "suspend" > /sys/power/disk
echo "disk" > /sys/power/state

Didn't notice that there was already a prior BZ for exactly this problem.
