To suspend, I'm using the "echo mem | disk > /sys/power/state" command. As of now, using suspend to RAM allow the machine to suspend, and resume is nearly OK except the video is not restored, and the screen stays black (but keyboard is Ok, I can launch any command I want, so I can restart). When suspending to disk, suspend is Ok with : echo -n 2097152000 > /sys/power/image_size ; echo -n disk > /sys/power/state and resuming detects the image in the swap partition. So, I have on the console, when I add "no_console_suspend" on the boot command line : PM: loading image data pages... PM: read xxxxx kbytes in y.zz seconds ... [stuff about scsi/sda] Disabling non-boot CPUs CPU1 is now offlone SMP alternatives: switching to UP code CPU1 is down and then, nothing :( machine is dead frozen. CAPS Lock doesn't toggle the keyboard LED anymore, I need to manually power off and power on the machine. I must add that these are my first attempts. So, this is not to be considered a regression. Is there anything else I can do to try to debug the resume ?
