Ubuntu 13.04 lenovo m490 INFO @wl_cfg80211_attach : Registered CFG80211 phy [closed]

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.

Solution 1:

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.
