    Can you try the following to get cleaner information:

    1. Make clean log files:
    Code:
    sudo mv /var/log/pm-suspend.log /var/log/pm-suspend.log.BAK
    sudo mv /var/log/syslog /var/log/syslog.BAK
    2. Initiate a suspend:
    Code:
    sudo pm-suspend
    3. Let the system suspend then wait for about 2 minutes. Then, initiate a resume.

    4. When the system has resumed, can you please post back the /var/log/pm-suspend.log and /var/log/syslog log files?

    And also, from your original post, how long exactly is "takes forever to resume from suspend"?
    From a suspension, it takes about 30-45 seconds. On Windows 7, it takes about 5 seconds.

    I tried using those commands, but when I get to step 4, it says the file doesn't exist.

    The commands to run are:
    Code:
    pastebinit /var/log/pm-suspend.log
    ...post back the link that is generated, and:
    Code:
    cat /var/log/syslog | grep PM:
    ...and post back the results that are displayed.

    That was the first one. I typed in the second one, and it didn't work. Said the file didn't exist.

    Hmmm. Lets try this again with a small change (I'd really like to see the two log files together):

    1. Make clean log files:
    Code:
    sudo mv /var/log/pm-suspend.log /var/log/pm-suspend.log.BAK
    sudo touch /var/log/syslog
    2. Initiate a suspend:
    Code:
    sudo pm-suspend
    3. Let the system suspend then wait for about 2 minutes. Then, initiate a resume.

    4. When the system has resumed, can you please post back:
    Code:
    pastebinit /var/log/pm-suspend.log
    ...and
    Code:
    cat /var/log/syslog | grep PM:

    The last line returned nothing. I typed it in, then it returned a new line to type a new command.

    That is very odd. Can you try one more time with these instructions (slightly modified again)?

    1. Make clean log files:
    Code:
    sudo mv /var/log/pm-suspend.log /var/log/pm-suspend.log.BAK
    sudo chown syslog:adm /var/log/syslog
    2. Initiate a suspend:
    Code:
    sudo pm-suspend
    3. Let the system suspend then wait for about 2 minutes. Then, initiate a resume.

    4. When the system has resumed, can you please post back:
    Code:
    pastebinit /var/log/pm-suspend.log
    ...and
    Code:
    cat /var/log/syslog | grep PM:
    Hopefully this time we'll get something.

    Well, I don't know what else to do. I tried the command again. Still nothing.

    Good its working again.

    From your pm-suspend.log file, resume takes 1 second, Not bad, except thats not what you're seeing.
    Code:
    Fri Jul  5 11:00:22 EDT 2013: Awake.
    Fri Jul  5 11:00:22 EDT 2013: Running hooks for resume
    .....
    Fri Jul  5 11:00:23 EDT 2013: Finished.
    From a suspension, it takes about 30-45 seconds. On Windows 7, it takes about 5 seconds.
    When you say 30-45 seconds, are you timing just the resume part, or is this the whole suspend/resume cycle?



    One other thing that I'm noticing is that from your syslog file, there are a boat load of acpi errors:
    Jul 5 11:00:22 Coder kernel: [63222.714716] ACPI Error: [DSSP] Namespace lookup failure, AE_NOT_FOUND (20120320/psargs-359)
    Jul 5 11:00:22 Coder kernel: [63222.714729] ACPI Error: Method parse/execution failed [\_SB_.PCI0.SAT0.SPT0._GTF] (Node ffff8802138779b0), AE_NOT_FOUND (20120320/psparse-536)
    Jul 5 11:00:22 Coder kernel: [63222.715281] ACPI Error: [DSSP] Namespace lookup failure, AE_NOT_FOUND (20120320/psargs-359)
    Jul 5 11:00:22 Coder kernel: [63222.715294] ACPI Error: Method parse/execution failed [\_SB_.PCI0.SAT0.SPT0._GTF] (Node ffff8802138779b0), AE_NOT_FOUND (20120320/psparse-536)
    Can you post back the results of this command to show which kernel parameters you are using?
    Code:
    cat /proc/cmdline
