Under load (4 megabyte/s) wifi stops working with the below messages in
dmesg. I rmmod iwlwifi and modprobe it again and then things start
working. This happens from time to time for me on this Thinkpad X200 with
"03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300".
Any other info I can provide to help fault finding this?
