The no_console_suspend seems to cause the system to not suspend/resume properly. Without the option: root@ts3:~# echo mem > /sys/power/state PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.01 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. Suspending console(s) (use no_console_suspend to debug) PM: suspend of devices complete after 109.710 msecs PM: late suspend of devices complete after 0.305 msecs Wake up daisy chain activation failed. Successfully put all powerdomains to target state PM: early resume of devices complete after 0.061 msecs PM: resume of devices complete after 304.229 msecs Restarting tasks ... done. root@ts3:~# With the option: root@ts3:~# echo mem > /sys/power/state PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.01 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. PM: suspend of devices complete after 106.811 msecs PM: late suspend of devices complete after 0.305 msecs (the current is quite high at this point, so I don't think we ever got into suspend) is no_console_suspend working for other people? Thanks, Cliff
