wireless chip reinitialized (b43)

[Mihai DonÈu]

Hi,

I'm an exclusive wireless user (at home, at least) and a pretty happy
one too. However, today something didn't go right:

I'm pretty used with the "transmission error" messages, but the
"interface stopped/started" are new and had the effect of "locking"
me out of the network (so to speak). I had to reinitialize the
interface via:
  # /etc/init.d/net.wlan0 restart

Is this new to everyone?

I'm using a 2.6.26 vanilla kernel:
  # uname -a
  Linux mdontu-dell 2.6.26 #2 SMP PREEMPT Tue Jul 15 00:19:02 EEST
  2008 x86_64 Intel(R) Core(TM)2 CPU T5500 @ 1.66GHz GenuineIntel
  GNU/Linux
on a DELL Latitude D520, with a:
  0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g
  (rev 01)

Thanks,

PS: This is the first time it happens to me and I don't know how to
reproduce it. I'm sorry.
