Using network manager in PC-BSD to add/configure a WPA enabled wireless network will result in iwn(4) becoming completely unresponsive. ifconfig up/down/scan will not do anything. The system will work *just fine* after a power cycle of the laptop. Setting the wireless switch off/on does not fix the issue either and there are no messages in the system logs to indicate what is going on. This seems to happen on Lenovo Thinkpads T420/T520 with the following wireless chipset. iwn0@pci0:3:0:0: class=0x028000 card=0x13118086 chip=0x00858086 rev=0x34 hdr=0x00 vendor = 'Intel Corporation' device = 'Centrino Advanced-N 6205' class = network bar [10] = type Memory, range 64, base 0xf5100000, size 8192, enabled >How-To-Repeat: >Fix: Requres a power cycle of the laptop. >Release-Note: >Audit-Trail: >Unformatted:
