Laptop hangs after closing and opening lid or unplugging power

For the past couple of months, whenever I close my laptop lid and open it back up, after a short amount of time the OS will completely freeze, I can't move the mouse, the keyboard is non responsive, the screen stops updating, and whatever sample of sound I'm running loops indefinitely. If I wait for an extended amount of time (generally more than 2 minutes) it will usually work just fine for a couple of minutes, then do the same thing again. After I've had the laptop up for some time, it will eventually stop. Once it kernel paniced and it seemed that it broke in a kworker thread, and the few times I've been looking at my processes when it occurs a kworker thread is running and taking up all my cpu (I don't know which one because by the time it shows itself, I can no longer get any response from my computer). This also occasionally happens when I plug in or unplug the power source. I haven't found anything suspicious in the log files, but I'll admit that I'm not quite sure which log to look at.

I'm using xmonad with gnome3, so power management should be being handled by gnome's power manager.

My Daemons:

DAEMONS=(syslog-ng dbus gdm network netfs crond sshd avahi-daemon net-auto-wired net-auto-wireless samba smbnetfs !hwclock ntpd)

The laptop is not overheating.
