Subject: Suspend wakes right back up

Hello,
My laptop will, after a short while, wake right up after issuing the command
pm-suspend.
The computer does not need to be connected to the internet.
I Get no errors and pm-suspend returns 0.
This tells me that the kernel must have some sort of wakeup event set.

The output on syslog is as follows (includes dmesg output):
