Hi Ryan- Haven't tried that either, but we can. Was hoping a known bug ID would bubble up, but this is also worth trying.

We have a similar problem when using midspan injectors. Does disabling CDP and then re-enabling it fix things? I believe our midspan understands LLDP but not CDP and the power negotiation between AP and switchport through the midspan was the issue.

I haven't seen something exactly like this before, but one time, "clear int gig0/1" (or whatever) solved a power issue on a 3560G PoE with an oddball camera.
