I've installed Ubuntu 13.04 (latest updates, kernel 3.8.0-25-generic) on this machine and got several issues:

When I restart the laptop the monitor displays:

[    9.171781] INFO @wl_cfg80211_attach : Registered CFG80211 phy

I don't know if it's a known bug in this combination. The issue is common known on other hardware configs.

I get the message.

I hope anyone can help me to identify if it's a bug or not.

I get the same message in 13.10 on my Lenovo Z565. Doesn't affect the boot, except perhaps slowing it down. –  Christopher Aug 27 '13 at 20:36

Looks like a bug: bugs.launchpad.net/ubuntu/+source/linux/+bug/1160322 –  Glutanimate Sep 9 '13 at 15:59

@Glutanimate is not a bug. Just a INFO message. –  Braiam Sep 10 '13 at 2:01
    
@Braiam I don't think it's intended behaviour to disrupt the boot up process with an extra black screen and info message. It doesn't matter if it has no effects on the WLAN function. An annoying message that might scare some users is just as much of a bug as an error that compromises the whole system. In this case I can talk out of personal experience as I am facing the same issue. And I can most definitely tell you that this is something new that has never occurred for me before Linux 3.8. –  Glutanimate Sep 10 '13 at 12:57
    
@Glutanimate if you check the "bug" report, you will see that is marked as INVALID and the very message you see starts with INFO [ 9.171781] **INFO** @wl_cfg80211_attach. In any case my answer is correct, and the problem is elsewhere. –  Braiam Sep 10 '13 at 13:57

According with this comment:

I got the same message on startup, but I don't think it's a bug. Just it's annoying message on startup

Next:

The same INFO message for me: I have the message each time at startup just before Ubuntu splash screen.

Is just a message, nothing to be scared of.
