| |
Hi, I have only now managed to move to 4.9-rc5 (from 4.8) and started seeing quite a lot of following messages " [ 346.612211] wlan0: AP c0:4a:00:f1:48:f2 changed bandwidth, new config is 2472 MHz, width 1 (2472/0 MHz) [ 352.655929] wlan0: AP c0:4a:00:f1:48:f2 changed bandwidth, new config is 2472 MHz, width 2 (2462/0 MHz) "
It always seems to be changing width from 1 -> 2 and back
$ dmesg | grep "changed bandwidth" | wc -l 42 in 13 minutes of uptime. I have noticed this came in via 30eb1dc2c430 ("mac80211: properly track HT/VHT operation changes").
Is this something to be worried about? -- Michal Hocko SUSE Labs
