So I tried - and I did not catch any lockdep output before the crash.
Unfortunately I do not have another machine on the same local network to
catch any messages after the crash... So I could be missing some warning
(I did synchronous logging though).
Will check with netconsole tomorrow.

Could you try if this patch changes anything?

...and maybe CONFIG_PACKET_MMAP turned off.

Ok. Removed the skb_orphan and turned of CONFIG_PACKET_MMAP. Seemingly 
the same game.
I now had another computer to catch the netconsole output. Still no 
lockdep warnings.

Unfortunately the other computer was a windows machine with its strange 
terminal, so long lines are wrapped at 80cols, but that shouldn't be too 
bad.
