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

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Device #13 (LID0) is the lid, and #11 (XCHI) is the USB xHCI controller. If I
disable both, suspend works well again:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solitone@alan:~$ sudo acpitool -W 13; sudo acpitool -W 11
[...]
Changed status for wakeup device #11 (XHC1)

The thing is that now I can wake the system up only pressing the power
button--neither the keybord nor the trackpad does.
