[SOLVED] Anybody else having a problem with resume from suspend to disk with kernel 3.14.3+ ?

I am curious to know whether anybody else is seeing a problem with resume from S4 (suspend to disk) with the latest kernels in -current (3.14.3 and 3.14.4).
On my netbook, on resume from S4, the system starts up and then hibernates again. If I then resume again, the system starts and all is OK.
The only clue I have seen is a slight difference in the dmesg output.
On first resume

Code:

[ 6587.879162] ata3: SATA link down (SStatus 0 SControl 300)
[ 6587.879192] usb 5-2: reset high-speed USB device number 2 using ehci-pci
[ 6587.881115] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 6587.882564] ata1.00: ACPI cmd ef/10:03:00:00:00:a0 (SET FEATURES) filtered out
[ 6587.884765] ata1.00: ACPI cmd 00/00:00:00:00:00:a0 (NOP) rejected by device (Stat=0x51 Err=0x04)
[ 6587.885177] ata1.00: configured for UDMA/133
[ 6587.885352] sd 0:0:0:0: [sda] Starting disk

while on second resume

Code:

[ 6590.881182] usb 5-2: reset high-speed USB device number 2 using ehci-pci
[ 6590.881192] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 6590.882669] ata1.00: ACPI cmd ef/10:03:00:00:00:a0 (SET FEATURES) filtered out
[ 6590.882712] ata3: SATA link down (SStatus 0 SControl 300)
[ 6590.884801] ata1.00: ACPI cmd 00/00:00:00:00:00:a0 (NOP) rejected by device (Stat=0x51 Err=0x04)
[ 6590.885208] ata1.00: configured for UDMA/133
[ 6590.885386] sd 0:0:0:0: [sda] Starting disk

Perhaps some race condition?

The deafening silence tells me all I need to know.

Just found the answer to my problem.
I trigger suspend to disk by closing the lid. The button/lid event then runs /usr/sbin/pm-hibernate from within /etc/acpi/acpihandler.sh
I find that I need to add an additional check on the lid status (shown in bold) to avoid the second hibernation event.

Code:

lid) grep -q closed /proc/acpi/button/lid/LID0/state && /usr/sbin/pm-hibernate

I was going to say good morning but you are most likely sleeping.

This seems to be my problem also

Novice
I could find my way to the folders but got lost after that.
Would appreciate a little more detailed instructions if you have time

Thank you Allend

Good morning and welcome to LQ!
This is the complete script.

Code:

bash-4.3$ cat /etc/acpi/acpi_handler.sh 
#!/bin/sh
# Default acpi script that takes an entry for all actions

IFS=${IFS}/
set $@

case "$1" in
  button)
    case "$2" in
      power) /sbin/init 0
         ;;
      lid) grep -q closed /proc/acpi/button/lid/LID0/state && /usr/sbin/pm-hibernate
         ;;
      *) logger "ACPI action $2 is not defined"
         ;;
    esac
    ;;
  *)
    logger "ACPI group $1 / action $2 is not defined"
    ;;
esac
