Now it always resumes immediately after suspend. I have no idea why initially suspend worked ok, then it started to work only intermittently, and now it never works. Anyhow, it depends on the the wakeup capable devices. Here's is the default configuration: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ solitone@alan:~$ acpitool -w [sudo] password for solitone: Device S-state Status Sysfs node --------------------------------------- 1.
