Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information.

Please include the information as separate attachments:
 * Output of uname -a
    * uname -a > uname.txt
 * Output of sudo lspci -vvnn
    * sudo lspci -vvnn > lspci.txt
 * Output of sudo dmidecode
    * sudo dmidecode > dmidecode.txt
 * Try to suspend/hibernate and then restart the system and attach /var/log/kern.log and /var/log/kern.log.0
 * Tarball of /proc/acpi directory. You can't just tar all files because their content sometimes changes etc.
    * cp -r /proc/acpi /tmp
    * tar -cvjf ~/acpi.tar.bz /tmp/acpi
    * attach acpi.tar.bz from your home directory

Hi,

Thanks for the quick response; here is the input.

Thanks Vorik, but there doesn't appear to be any evidence of a suspend/resume attempt in your kernel logs. Could you try to suspend/resume your machine, then annotate the line in your /var/log/kern.log where you think the suspend begins (identified by timestamp).

Thanks in advance.

Hi,

When suspending/resuming again; I found that the latest update apparently solved the issue. 95% of the suspend-resumes go as planned.

Thank you very much for your support; this bug can be closed.

Vorik.
