because we thought we'd fixed the rtnl_lock() problems in 2.6.21-rc7-mm2.
Are you sure that log is from 2.6.21-rc7-mm2?

Yes. I have retested it another time ( for adding the small usb debug 
message ) and get the same message a new time.

Maybe a tiny difference : only eth0 was setup during boot ( bond0 and eth1 was 
not setup - volontary  - to avoid problem that could interfere with usb ). 
Ony after having done my usb test, i have stopped the eth0, setup bond 
interface and restart bond interface and got the same problem with the same 
back trace.

OK, thanks.

The failed RTNL assertion here is unrelated to the mutex initialization
bug in 2.6.1-rc7-mm1. The bonding driver is not holding the rtnl_mutex
while calling dev_set_mac_address (and can not since its called from
a timer). I believe this is a known problem to the bonding maintainers.
