When suspending to mem, actually it "looks like" it suspends. The only thing is that the LCD stays "light grey" (yep, I know it is not a technical description... :). In order to resume, I have to press the thinkpad power button (tap it, if I hold it for several seconds, it just powers off). When resuming, there must be a problem with interrumpts (NIC and Trackpoint stop working). So, it is not "immediate"

Suspend to disk does not work (If I don't kill artsd, cf. previous message). If I kill artsd first, : Stopping tasks: ================================================================ =======| Freeing memory: .........................................................| hda: start_power_step(step: 0) hda: start_power_step(step: 1) hda: complete_power_step(step: 1, stat: 50, err: 0) hda: completing PM request, suspend PM: Attempting to suspend to disk.

In both cases, when suspending to disk, it returns immediately.
Thanks, R.
