I'm trying to send my system to sleep using e.g.
rtcwake -v -m disk -s 60
and receive the following output
rtcwake: RTC wird als UTC interpretiert
UTC wird verwendet.
delta = 1
tzone = 0
tzname = UTC
systime = 1524206927, (UTC) Fri Apr 20 06:48:47 2018
rtctime = 1524206926, (UTC) Fri Apr 20 06:48:46 2018
Alarm 0, sys_time 1524206927, rtc_time 1524206926, Sekunden 60
rtcwake: wakeup from "disk" using /dev/rtc0 at Fri Apr 20 06:49:47 2018
suspend mode: disk; suspending system
rtcwake: write error
The system seems to start entering the suspend mode but returns back immediately. I'm running Ubuntu 16.04.4 LTS (GNU/Linux 4.13.0-38-generic x86_64). Are there any details, that would help to find the root cause of the problem (dmesg output, /var/log/syslog, ...)?
Thanks in advance,
Bernd
mem
instead ofdisk
with -m switch? I am guessing hibernation is not possible on the machine since there is not enough swap mem, have you checked this? I am guessing that is the reason why it returns immediately.hpet=disable
works for me, too. Added it toGRUB_CMDLINE_LINUX_DEFAULT
in/etc/default/grub
on my debian server
