Bootprocess stops at "Oct 1 11:53:40 bt kernel: [ 52.968917] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready"

Hi,

im using BT5 KDE HDD installed on my netbook. Wireless connection works fine for me, but there is this problem that annoyes me. When BT is aboute to boot everything is fine until logon. it pops up normaly and than a few seconds later i get this output:

PHP Code:
Oct  1 11:53:24 bt kernel: [   37.408201] b43-phy0: Loading firmware version 508.1084 (2009-01-14 01:32:01)

Oct  1 11:53:40 bt kernel: [   52.968917] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready 
after that, nothing happens until i hit enter. than the normal loginscreen appears.

I did a research and found out, that b43-phy0 is like a driver for the a/g/n chipset.

1. does it make sense to update the b43-phy0 driver?
2. can i gather more information aboute this error respectively, where can i find some more details of such errors?
3. how can i find out which chipset is on my w-lan card?

thanks in advance.
