Thanks for the quick reply, Jonathan. > Is this a regression?
Not really (the machine is new). I tried older debian 5.09 and 6.03 live cds. With 6.03 suspending from a session worked under some conditions (lid) but not all (menu). > Does suspend-to-disk > (triggered with > > echo disk >/sys/power/state This doesn't work. > ) work?

For some reason I didn't find it while searching around (we beginners don't know to search for "pm-" instead of "suspend"). Maybe a link could be added on the debian wiki at http://wiki.debian.org/Suspend ? The "shutdown" method described in the document seems to work. But it is a bit clunky and it wasn't immediately obvious how to set this option permanently or whether it even applies to suspend to RAM (more for the wiki...) In the meantime I found the following site http://thecodecentral.com/2011/01/18/fix-ubuntu-10-10-suspendhibernate-not- working-bug and shamelessly copy-pasted the suggested script. It works pretty well - the only obvious problem at the moment is that waking from sleep requires a press of the power button (lid-opening doesn't suffice). But at least there is no freeze with data loss and reboot. Huge progress. The working "shutdown" method suggests a bios issue and the copied script indicates a usb problem. Follow up might therefore look at the usb settings in the bios and investigate a bios upgrade (the changelog mumbles something about usb). The comments on the web site suggest that the solution has helped a lot of people and with different machines.
