b43 problem.

[Omri Schwarz]

Hi, all. I'm running FC 10 on a Lenovo 3000 C100 laptop
with a Broadcomm 4318 wireless driver. A problem developed today
that shows as follows in dmesg:

fuse init (API version 7.9)

ADDRCONF(NETDEV_UP): wlan0: link is not ready

This happens when I try to bring the interface up first time after 
booting.

That is, it finds the local network, associates with the
access point, and tries DHCP, and then instantly drops out.

I'm wondering if it's the chip dying, since Google doesn't show any other
cases like this.

So, anyhow, here are the kernel details:

Linux localhost.localdomain 2.6.27.25-170.2.72.fc10.i686 #1 SMP Sun Jun 21 
19:03:24 EDT 2009 i686 i686 i386 GNU/Linux

Anyone seen anything like this? Thanks for your attention.
