Description Stefan de Konink 2006-12-05 09:41:58 UTC 
Most recent kernel where this bug did *NOT* occur: 2.6.18-r3
Distribution: Gentoo
Hardware Environment: iBook G4
Software Environment: Any
Problem Description:

After I upgraded to this kernel version my airport broke entierely inside Mac
OSX. Resulting in a kernel panics on OSX, OpenFirmware illegal instructions,
etc.. I'll post the same error on the gentoo bugzilla for this incident. It
could be completely coincidental, but better safe than sorry. 

Steps to reproduce:

Upgrade to 2.6.19-gentoo-r1, boot back to OSX, get iBook to sleep. *death*. In
order to get it to boot again I resetted te logicboard by Fn-Power, I could boot
back in Linux and safe my data. 

The MacOSX crash is easy reproduced. If the airport is on, the system will
crash. If you turn the airport on the system crashes.



Again, I'm not entirely sure if the kernel upgrade caused this. But before I'm
going to send my iBook for repair I want to make sure this isn't some (bug) in
Linux, doing something nasty with the hardware.

Comment 1 Chris Wedgwood 2006-12-05 10:05:00 UTC 
I would call this a bug with the OS X drivers.
Comment 2 Stefan de Konink 2006-12-05 10:20:15 UTC 
The guys at two different independent Mac-shops said it sounded like a hardware
issue. As I mentioned if this bug was triggered by Linux because of the bcm43xx
driver, it would be foolish to ignore the knowledge, get a hardware replacement
(& two weeks without an iBook), and break it again.

I'm going to see if it can be fixed with software or if there is any mac
diagnostics that can access the device without drivers.
Comment 3 John W. Linville 2006-12-05 11:01:33 UTC 
Does the device still work in Linux?  Or is broken there too?
Comment 4 Stefan de Konink 2006-12-05 11:19:46 UTC 
It did never worked with Linux in a stable way. Using 2.6.9 (iirc) I could ping,
but not much more. This is know by the bcm43xx developers. (Because they did not
implement the signal strength code.)

I found out that I'm not alone the last days with the *same* issue in OSX.
http://forums.macosxhints.com/showthread.php?p=337100

Now I guess it has nothing to do with the Linux upgrade. But the amount of
people with the same problems (including the same security updates) makes one
wonder how this update ever passed the quality tests.

Should I put this bug under Invalid or Documented?
Comment 5 John W. Linville 2006-12-05 11:29:32 UTC 
Sounds like you have 4318 hardware, which is known to be unsupported with 
current Linux drivers.

Anyway, this does not seem to be a Linux problem.  Good luck in your dealings 
with Apple's hardware support.

I leave this bug as invalid. But from an objective look, would this be hardware
or an firmware that is broken?

And this one is with an 'old' firmware file... so we can conclude we can break
Linux too...
Comment 8 Stefan de Konink 2006-12-13 13:47:31 UTC 
Ok, I removed power etc. I didn't have the 'problem' when inserting the kernel
module. But ifconfig eth0 up resulted in a 'Bus Error' again:

*Nothing changed* rebooted. Now bcm43xx is eth0... I can do iwconfig up. And
only get the 'default' error message.
