 I've just tried again.
 Once with the non-lockdebug kernel since that's what I was running,
 opening the 14 files lead to a reboot without a crashdump.
 
 dmesg after reboot started with:

 Then I tried with a lockdebug kernel. First try was interrupted
 because there were lock files still lying around from the previous
 try, after I removed them, it worked without panic.
 
 I tried again in a different directory but couldn't reproduce it there
 either.

 Yes, I've closed it. Thanks!
