For the config, i have uploaded it to 

For reproducing the problem, it 's simple (for me at least) :

	-  setup a bonding interface ( IP so nothing 
fancy ) bond (mode 6 : alb ) on two NIC card (in my case  E1000 and TG3 ). 
Don't know if it's important or not but the two cards are connected to the 
same cheap 100Mb switch ( So no gigabit )

	- Reboot  : when the bond interface went up ( after the two physical slaves ) 
the bug is triggered ( for the moment always, but i have only rebooted 2 or 3 
times with 2.6.21-rc7-mm2  ).

	- You could also play with networks cable and put down/up one interface or 
another  during normal work : it would often triggered the same trace ( not 
always although ). You don't need to have load on the network. The interface 
that went down or up doesn't seem to be important as far as i can see.

	- No lockup of the kernel, network still work fine after the problem
