But, it only works with CONFIG_NO_HZ unset. Setting CONFIG_NO_HZ will cause suspend to disk to hang just before saving memory to disk. Resume from RAM (s2ram) still broke (tried with or without CONFIG_NO_HZ). Suspend to RAM seems ok, but upon resume, the screen will only display "inu" and only after pressing the power button will the system return to console. But "date" still doesn't advance. Thanks, Jeff.
