2.2.14pre17 hangup with SMP during ifconfig

I try to run SMP on a dual PIII450 using 2.2.14pre17.
I got several hangups, where as the non SMP kernel seems to be
stable for me. I can reproduce a system hang during network
shutdown. I'm using a 3x905C with a driver module 3c90x supplied
by 3com, so may be there is a bug within this module which is not
part of the official linux kernel. I traced it down to the last
system call of "ifconfig eth0 down":

ioctl(4,SIOCGIFFLAGS, 0xbffffc80) = 0
ioctl(4,SIOCSIFFLAGS, -- hangs ---

I then tried to put some printk() into net/core/dev.c, but I got
no response. I'm not even sure if dev_ioctl() was reached or
if it got lost before. Who is calling dev.c:dev_ioctl()?
