Can't find culprit of 100% CPU on AP1142N

My CIsco LAP 1142N running in autonomous mode is reporting constant 100% CPU usage. It seems to work fine, though the other night I got home and it wouldn't let anything connect to its SSID (reboot fixed it)

Here is a log of what's running:

This is my first time using a Cisco AP. I upgraded the firmware to the latest release and it's still at 100%. Any ideas?
 
Offhand I can't see anything there using virtually any CPU. Is this by chance hooked up to a switch with other VLANs on it that aren't being pruned from the AP's port? Or is there a loopback interface configured on the AP?

What does "show log" show?

No loopback. It's running off an older 2950 switch. I only have two VLANs on the whole network, one of which is VLAN 1.

Does PoE make a difference? It's running off a TP-Link 802.3af adapter

This is pretty much all the event log shows.
