Hmm, compiling and booting several dozen kernels isn't time consuming? 
Then I must have done something wrong in the past.

And I wonder why I've writen descriptions at all, if nobody wants to 
understand that I already know the patch which leads to a broken network 
on that system.

If the patch is really the reason for the problem, is something totally 
different, but bisecting won't help here. Besides that I know since 4 
years that netconsole is broken on that box, it just never broke the 
network or anything else. And so I ignored it, foreseeing the necessary 
time to debug and especially describe and discuss the problem.

You see, I'm already feeling like just talking with myself. But just in 
case: After reverting patch 7cd1463, there exist a online-change to turn 
on/off the problem:

------
------

Thats basically just what the reverted patch does. Now, why should I 
still bisect?

Of course, my first assumption that the changed reset is the bug is 
wrong, it just makes the problem to appear. But that wrong assumption 
still doesn't make a bisect necessary. And it's discouraging if people 
still insist on that.

I will see if I spend the time to write down a more detailed description 
about what happens here.

Regards,

Alexander Holler
