I have not experience this time delay on Gutsy or Feisty. I'm not sure if the error occurred on previous installations, but if it did, it didn't cause such a long a delay.

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

* Try to suspend/hibernate and then restart the system and attach /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
