Description v1ne2go 2014-02-28 13:30:53 UTC

If you activate "SaveClock yes" in /etc/hibernate/common.conf and have services installed that depend on the "clock" service, they are also stopped during suspend, but not restarted afterwards.
This might only apply to systems using OpenRC, which I use (sys-apps/openrc-0.12.4).
In my case, this affects fcron:
# /etc/init.d/hwclock -Z stop
 * stop: fcron hwclock
#

I expect only hwclock to be stopped.

Reproducible: Always

Steps to Reproduce:
1. Use OpenRC, install fcron and hibernate-script
2. Activate "SaveClock yes" in /etc/hibernate/common.conf
2. ps ax -> fcron runs
4. # hibernate
5. resume your system
6. ps ax -> no fcron runs
Actual Results:  
fcron is stopped and remains stopped

Expected Results:  
fcron keeps on running.

I fixed this by ignoring hwclock's dependencies when stopping it, see the attached patch.

Hi,

Can you please checkout the following instead:

+           /etc/init.d/hwclock save > /dev/null 2>&1

and:

+           /etc/init.d/hwclock restart > /dev/null 2>&1

BTW: on recent kernels it is better to configure CONFIG_RTC_HCTOSYS than using this option.

Comment 3 v1ne2go 2014-03-26 12:21:04 UTC

This change also works for me.
Thank you for looking at it!

As suggested, I will be switching to clock_hctosys="NO" in the future. Thank you for the hint.
