Hi Ralf,

I wanted to check FPAC ROSE application behaviour when Ethernet link was 
shutdown.
To do this I removed the ethernet connector !
I agree this was a very agressive action.

The message hints that disc_data_lock is aquired with softirqs disabled,
but does not itself disable softirqs, which can in rare circumstances
lead to a deadlock.

Does this fix it?
If so, drivers/net/hamradio.c, function sp_get() would probably need the
equivalent fix.  Same for drivers/net/ppp_async.c:ap_get() and sp_get() in
drivers/net/ppp_synctty.c.
