Sleep / hibernate seriously crashes Gnome on AMD64

I should add two things: First, this problem is consistently replicable--every time I suspect or hibernate, gnome crashes. Second, the problem first occurred just after I installed Ubuntu, so I think this is not a matter of interactions with software I've since installed. On the Gentoo website, gnome-power-manager-2.20.1 is hard masked for AMD64, indicating they have run into serious problems w/ that version on AMD64.

It seems that Gentoo has hard masked it for all architectures:

Which is likely because of this bug:

Which is reported fixed:

http://bugzilla.gnome.org/show_bug.cgi?id=497908

Just to be clear though, you're saying that suspend works on your computer under Gentoo?

Hi Ted: Thanks for the reply! You're right, it is masked for all architectures. I have not, however, tried gnome-power-manager under Gentoo on my computer. I simply noticed that the recent version of the power manager was hard masked in Gentoo because I thought that's what was running under Ubuntu. Actually, on closer inspection, Ubuntu is running what looks like a slightly earlier version that has been modified for Ubuntu. That earlier version (though not modified for Ubuntu) gets a clean bill of health in Gentoo for AMD64, according to the portage page. But, I haven't tried it.

Just to be clear: The version of gnome-power-manager running under Ubuntu *should* work for AMD64, but it does not on my AMD64 system. This leaves several possibilities, among them: the report on the Gentoo site saying gnome-power-manager works for AMD64 is false (which is unlikely) or something done by Ubuntu to adapt that version of gnome-power-manager to Ubuntu has created a bug.

So Ubuntu experts: strike one against global warming by fixing this problem!

I have the same problem, but I am running Ubuntu on a brand new stock laptop. Intel Core Duo. Problems started occuring when I enabled suspend/resume. I can never resume without crashing the OS. On resume, the screen blinks a few times, goes to terminal mode, and complains:
Dec 22 19:38:04 totic kernel: [ 4012.488000] usb_endpoint usbdev4.8_ep00: PM: resume from 0, parent 4-1 still 1
Shortly afterwards, system goes into hard reset. This happens every time.

Workaround: do not suspend.

If you need any more info, I'll be happy to try out solutions, collect logs, etc.

I also have a brand new 64bit laptop that consistantly crashes with a 64 bit Intel Core Duo 2.4ghz. It has a fresh install of Ubuntu 8.04 (no M$oft) and will consistently crash upon resuming a session . atotic stated the issue very well above.

If you use the laptop for any type of business, it can be a bit embarrassing if you forget and don't completely shut down since you know that upon wakeup it will crash and then you need to reboot. It is also tough to work without the suspend / hibernate function as the batteries seem to run out pretty quick.

I would also be happy to help if that is possible..

mtopro: sorry to hear about your having this problem. I know it's difficult enough to deal w/ on a desktop that I hate keeping on all day. Ubuntu 8.04 does, however, solve the sleep / hibernate problem for my AMD64 desktop. I'm guessing they Ubuntu wizards are working hard on this problem. I wonder if it may be an idea to report this separately as an 8.04 problem?

Good idea slowtrain. Thank you, I will do it.

Is this symptom still reproducible in 8.10?

H Daniel: No, I've not had this problem in 8.10--thank heavens!

Thank you for your feedback. Because it seems you are no longer experiencing this bug, I will close this bug report now. Please feel free to report any other bugs you find.
