I read the above and understand that it suspends twice when you have manually entered 'hibernate-ram --force'. Does it also have that problem if you suspend upon lid close? That part was not clear to me. Or is it only when you manually call hibernate-ram? I always use Fn-F4 (sleep) on my T60 and then close the lid and do not have this problem. I don't sleep automatically on lid close. I often want to close my lid and carry from place to place and don't want it to automatically suspend. However my T60 is currently Squeeze not Wheezy so the versions are not the same. I do have acpi-support installed. I do not have LID_SLEEP=true uncommented. I assume you have scanned the /var/log/syslog looking for the event trail? Is there anything interesting there? If things haven't changed in a release look for "PM:" lines. > It seems pretty clear that somehow, the lid closure is triggering a > second hibernation, which takes place after the machine wakes up from > the first (even though the closure occurs after the machine has already > gone to sleep). This is certainly not the desired behavior - is this is > bug? Should I file against acpi-support? I have read of people having this problem before. There is almost certainly discussion in the debian-laptop mailing list from some years ago on this problem. I am sure you are not the only person to have suffered from suspending again immediately after waking from sleep problem. But I am not sure if or where a bug would lie. Plus I assume that systemd has absorbed all of this functionality in Jessie therefore filing a bug report would simply be ignored now. Bob
