In an attempt to learn more on the command-line I added Debian-7.4-Standard to my Acer-Aspire-One laptop. I am not sure as to what I did exactly, but after I managed to install the non-free firmware and manually installed network-manager to get a wired connection that worked well enough to use apt-get update and apt-get dist-upgrade, I started to see a strange message on my login prompt after I had booted into my Debian OS. I wrote out a copy of it and it looks like this on my login prompt:

Debian GNU/Linux 7 debian tty1

debian login: [   17.63024] ieee80211 phy0: brcm_ops_config: change monitor mode: false (implement)
[   17.630399] ieee80211 phy0: brcms_ops_config: change power-save mode: false (implement)
[   17.631562] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement)

What does this mean? Is this a problem I need to worry about?

If I hit enter the login prompt returns to just the usual debian login: prompt and I can login normally.


Update: I just noticed that when there is no WiFi signal my login prompt acts in the normal way. I am only seeing these messages when a WiFi signal is available.

    Those are kernel log messages, easy to recognize because of the [ 17.63024] prefix with the uptime. As for what those messages in particular mean: no idea, but they seem related to wifi (ieee80211 phy0 suggest some wifi-antenna drivers). – Darkhogg Apr 27 '14 at 22:42
  • It's probably possible to selectively suppress such messages. – Faheem Mitha Apr 27 '14 at 22:46
