Ok, I had time to test src/sys/net/if.c revisions 1.144, 1.145 and
1.146 on my system and got the same results as Matthias Scheler:
Revisions 1.145 and 1.146 produce sudden and complete hangups of my
i386 system (no removeable network device, just one fxp nic).
Reverting to revision 1.144 solved this problem on my machine, too.
