Same issue here after upgrading to Natty. Seeing 350 - 550 wakeups per second, however the top cause seems to be the "extra timer interrupt"
Backup reduced from 3 hours to 1hr 55 minutes now.
Wakeups-from-idle per second : 499.2 interval: 3.0s no ACPI power usage estimate available
Top causes for wakeups: 48.3% (303.3) [extra timer interrupt] 18.6% (117.0) chrome 12.1% ( 76.3) [iwlagn] <interrupt> 4.9% ( 30.7) [ahci] <interrupt>
