Hi,
I thought I'd enable suspend and resume on my desktop machine so I could save myself some time in the morning when I restart the machine. The machine is fairly standard Intel Core Duo based system (lspci attached). However when I execute pm-suspend (or Gentoo's own hibernate-script) the system does suspend but resumes immediately. To add insult to injury the ethernet doesn't come back properly and needs a reboot to reset it.
I've played about a little with the ACPI debug stuff but it's easy to overflow the dmesg buffer. The relevant section around the suspend/resume looks like:

Unfortunately the ACPI stuff is all Greek to me. If anyone wants additional debug information then please let me know.
So any ideas?
