Hi,

I've done some testing w/ our SMP machine and the PPPDs - the FREEZE (lock)
occurs due to the locking via rtnl_lock()/rtnl_unlock() for unregister_netdevice
in ppp_destoy_interface.
The problem occurs on 2.4.0.SuSE and all vanilla 2.4.x kernels (just tested
2.4.5) in SMP mode only!!!

(And yes, not locking the lists works BUT ... :-)

All help is very much appreciated!
Thanks in advance,

Immanuel

P.S. Please put me on CC: if you reply - makes my list sorting easier... :-)
