Hi,
Thank you for answer about hibernation. Can you help me with similar
issue with sleeping?
I can freeze system and wake it up with "echo freeze > /sys/power/state"
command, but system can't wake up from suspend to mem (that can be
started with closing display, pressing sleep button or with "echo mem >
/sys/power/state" command).
Log after freeze command attached. As far as I can see wakeup must be
possible with "sleep" button:
$ cat /proc/acpi/wakeup
Device S-state Status Sysfs node
HDEF S4 *disabled pci:0000:00:1b.0
USB1 S4 *enabled pci:0000:00:1d.0
USB2 S4 *enabled pci:0000:00:1d.1

USB6 S4 *enabled pci:0000:00:1a.2
EHC2 S4 *enabled pci:0000:00:1a.7

SLT6 S4 *disabled
LANC S3 *disabled
LANR S3 *disabled
SLPB S3 *enabled platform:PNP0C0E:00
LID S3 *enabled platform:PNP0C0D:00
When I power off notebook and restart it after sleep there is nothing
about sleep in logs.
Regards,
Nikolay
