Hi there,
I finally took the time to have a look after the crashes people reported
on linux-hams. The kernel oopsed on "ifconfig <iface> down" if there
were live connections via <iface>. I don't quite know if the attached
patch fixes the problem, but it seems to be reasonable. Please give it a
try.
Gruss,
Matthias
