Both removing the wifi driver and disabling compositing seem not to
change anything significantly.

Top causes for wakeups:
  38.1% (140.4)     <kernel core> : hrtimer_start_range_ns (tick_sched_timer) 
  17.6% ( 64.8)       <interrupt> : PS/2 keyboard/mouse/touchpad 
  11.0% ( 40.4)       <interrupt> : ehci_hcd:usb1, uhci_hcd:usb2, HDA Intel, i91
   6.3% ( 23.2)      <kernel IPI> : Rescheduling interrupts 
   4.7% ( 17.3)            chrome : schedule_timeout (process_timeout) 
   4.1% ( 15.1)       <interrupt> : ahci
