Description Alexei Podtelezhnikov 2008-03-31 23:01:43 UTC 
Here is some statistics in the best case scenario when I have a very good 
access point at home. b43 is second to ACPI by the amount of generated
messages in the logs.

[apodtele@home ~]$ dmesg | grep -c b43
43

At work this number is more like 843 given a poor access point.

Anyway, why reload firmware 7 times by now? I believe it didn't use to be lke
this. Is driver moving in the wrong direction? Please don't tell me this is
totally normal because it will sound like BSOD is by design.
  
[apodtele@home ~]$ dmesg | grep firmware

Comment 1 John W. Linville 2008-04-01 13:11:57 UTC 
There might be any number of reasons to reload firmware.  A quick perusal of 
the sources suggest that it is reloaded after suspend/resume, when recovering 
from certain errors, when changing some configuration parameters, and probably 
on ifconfig up as well.  I would need your complete dmesg output or contents 
of /var/log/messages and a more thorough description of your scenario to be 
able to comment further.

Are you experiencing real problems?  Or are you simply annoyed by the firmware 
loading messages?

No, I don't suspend/resume. I just use my laptop at work.
b43 know one way of dealing with errors: don't think -- reload the firmware.
This attachment contains 41 reloads. Crazy!
Comment 3 Alexei Podtelezhnikov 2008-05-04 02:44:49 UTC 
With recent kernel-2.6.24.6-90.fc8.i686, reloads stopped and firmware seems to 
be loaded just once. Cool.
