Cisco AP 3802 cannot join WLC - aptrace_register_sysproc_fn: duplicate registeration for 'wired'

Hi,

 

We have bought some Cisco 3802 Ap's. I connected 1 of the AP's to a switch we have at our office to see if it worked and it did. I read that there has been some bugs with the AP where if you connect it to a 100mbps port it will show you the "aptrace_register_sysproc_fn: duplicate registeration for 'wired'". 
I have now set up the antenna up on the right location, but we are using a POE which is 1gbps.

 

The problem is the same as with 100mbps... I have tried to google it, but so far I don't see any solution.

The WLC is running version 8.5.135.0 which is not the newest. I would love to update the version, but we can't since we also have 1602 AP's in our enviroment, so if we update 1 more version it doesn't support it anymore.

 

Does anyone have a good solution to make the 3802 AP to work with a POE?

 

Regards,

Jørgen

Could be this bug

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvi14641/?rfs=iqvred

Symptom:
Access point goes into a boot loop. The switch shows the link as up, but no CDP information.
The AP console shows messages similar to the following:

[*02/23/2018 18:40:50.3857] waiting for POE negotiation to complete
[*02/23/2018 18:40:52.9034] SYS-COND: AP is in critical condition
[*02/23/2018 18:40:55.3865] Waiting for uplink IPv4/IPv6 configuration
[*02/23/2018 18:41:08.3887] Resetting wired0, if[02/23/2018 18:41:08.4200] wired0: stopped
config down up
[02/23/2018 18:41:10.5000] wired0 emac 2: link up
[02/23/2018 18:41:10.5600] wired0: link up
[02/23/2018 18:41:10.6000] wired0: started
[*02/23/2018 18:41:10.6537] aptrace_register_sysproc_fn: duplicate registeration for 'wired'

Conditions:
- switch port speed is configured for 100Mbps (or, in some cases, a port configured for 1Gbps may come up in 100Mbps due to cabling)
- AP2802 or 3802 (problem does not affect IOS APs or 1800 series)

Workaround:
Change the switch port speed to 1000M, or use a power injector
