Fiddling with /proc/acpi/wakeup and kernel 4.1 seems to fix the
spontaneous wakeups on my macbook. However after a day, acpid seems to
see events like LID_CLOSE. Newer Ubuntu version will use systemd for
suspending so I am not sure what benefits I get from debugging this.

Interesting bug. I upgraded my Ubuntu 14.04 kernel (currently

What I suggested in my previous message didn't solve the problem and as
said by other the problem was Intel Rapid Start Technology.
What happens is that the firmware sets a wakeup timer as soon as the
laptop is suspended and doesn't cancel it if the laptop is resumed
before it expires. Linux is
Since the wakeups are random and doing tests is complicated, I'd like to
ask to all of you with this problem to try the following.
First, run the following command:
cat /proc/acpi/wakeup
Look at all the devices that are able to wakeup the laptop (those with

This happened to me a couple of times, maybe more.

up from suspend within that amount of time.
