For the past five years, I've been getting these 'crit' errors in my external log server. It doesn't seem to affect operation, but it is a nuisance. I've applied all of the firmware updates, but the issue persists. IMHO, this is a debug message that should not have a 'crit' severity. I get these only when roaming between access points, and typically once per week or so. It would be nice if one of the AP firmware developers could lower the severity of this message so I don't get unnecessarily spammed.
Example from this morning:
[14296717.091274] wmi_unified_mgmt_rx_event_handler-1864 : MGMT frame, ia_action 0x0 ia_catageory 0x3 status 0x0
