Hi,
I think this mail is off-thread, but I lost track on the way. Sorry for that.
Anyway: Within this thread a solution based on software-suspend2 was mentioned. I tried it and I'm quite surprised: it works!
I'm using 2.6.12 with dvb-kernel CVS + the patchset from suspend2.net + hibernate from debian. Some usb-driver-quirks were necessary and now my system is up and running within 20 seconds, which is quite enough for me (as fast as the old dbox1, afair).
I'm using vdr with softdevice via a Matrox G550 and 2 budget devices.
Thanks for mentioning suspend2, thanks for the good work on VDR and especially the soft-device-plugin.
What are the usb-driver-quirks that you mention? Are they usb DVB devices that you have?
I've just been having another go at getting software suspend to work on an Epia-based vdr system with vdr-xine. I can get it to suspend and resume fairly easily with a 2.6.12 kernel and the latest patch set form www.suspend2.net but I can't get the DVB drivers to play nicely!
A suspend and restart brings it back up as it should and vdr starts but all I see is a black screen. I can change channel but I still get a black screen. I have yet to see if the DVB card (an old l64781 based Nova-T) is outputting a stream or not, and LIRC won't allow any connections after resuming (homebrew receiver). I have yet to try playing back a recording because it's a bit awkward without a remote!
Has anyone had any luck with software suspend and this type of card or LIRC? Do I need to explicitly kill vdr and unload the drivers before suspending, and then reload and restart on startup?
Cheers,
Laz

Yes, I unload the DVB drivers before suspending and reload them after resuming. Because of the firmware load of the DVB-USB-devices (after firmware load they do a soft-reboot and appear as a "new" device) I had to add a small delay of 3 seconds, that's what I meant by quirk.

Hmm I would simply stop and start the drivers/services which don't survive the hibernation.
Do I need to explicitly kill vdr and unload the drivers before suspending, and then reload and restart on startup?
Have a look in /etc/hibernate/hibernate.conf - there are scriptlets-hooks which can be of help.
regards, Patrick.

Thanks for sharing your experience. That's very interesting because I'm trying to improve the boot-time of my VDR for some months.
Would a hibernated PC wake up by Wake-on-LAN or Wake-on-Ring?

If you have it enabled in your bios, yes.
Software Suspend2 is software based. It can but it does not need ACPI-sleep-modes from the bios. It dumps the memory to the harddisk and does a normal power-off.
When you boot the machine it loads the kernel normally and then it restores the memory from the harddisk.
I'm using the filewriter, so I don't need to repair the swap-space afterwards.
You just have to take care about incompatible modules (DVB) and services (VDR, because it depends on DVB). The hibernate-script (which I would highly recommend to manage software-suspend) is a very good help to work around quirks.
Patrick.
