This may be a one off, but I'm getting the following call trace. The full log will be attached along with dmidecode and lspci. Hardware is an HP Spectre laptop with intel wireless.

This is a bug in the AP. We shouldn't WARN so loudly though.
Thanks for the reply. AP is ISP (Xfinity) owned and managed unfortunately, and out of my control but for bug completeness. ARRIS Group, Inc. Model: TG1682G Hardware Revision: 11.0 eMTA & DOCSIS Software Version: 10.1.11.SIP.PC20.CT Software Image Name: TG1682_2.8p24s1_PROD_sey
Created attachment 274923 [details] fix This will make the driver code less noisy. It'll allow you to connect with HT as well since we'll now take the defaults WMM parameters.
