Hi all, I've installed CentOS 5.2 i386 (with all updates) on notebook Fujutsu Siemens Esprimo U9200 Suspending works normal, but after resuming my system crashes. There are no messages about that in /var/log/messages, only after reboot system I see in gnome: " Resume Problem Your system did not appear to resume correctly from Suspend/Hibernate. This may be a driver problem or a

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the

Hey, Sorry for dropping in like this, couldn't find any information on this and I guess I'm too lazy to read all the relevant bits and pieces of the kernel sources to find out: I'm currently running encrypted root and swap, but would still like to use suspend to disk. Would early userspace be capable of inserting the crypto-loop module into the kernel, load the keys off my

Let host know of our state (partial yet) so that the host PCI device is up to where we were when we were suspended. This is still an RFC as this doesn't completely work: an unused device at the time of suspend will work fine after resume, but a device that has seen some activity doesn't behave well after resume. Especially, host->guest communication doesn't go through. This could
