It just happened again today, after heavy CPU & IO load (rsyncing from/to 
external disks on dm-crypt). This time the oops was printed on the screen 
but nothing on netconsole:

It looks like the oops I reported earlier (oops2m.JPG) so I doubt it's a 
random corruption due to hardware issues...?

Any debug or boot options to set in my next kernel build?

Thanks,
Christian.
