It is at the moment, I'm afraid. I'm hoping to get SCSI support for suspend2 finished shortly. I did suspend a OSDL machine to SCSI in January, but the driver lacked the power management that I needed to reload the second half of the image and thereby be sure all was okay. > btw: would it be somehow possible to resume after initrd phase? > or some other idea how a generic kernel with modules in the initrd > could use suspend to disk? or a laptop where the initrd is needed > to setup a dm-crypt volume with the right decrypton key? That should be doable, provided that the initrd doesn't mount anything. Decryption is 'interesting'. The key needs to be set up in the resumed kernel too. (Shouldn't be a problem, if you manage to suspend to it!).
