Hm, removing the serial console boot line portion still causes a 
spontaneous reboot. Same for removing /bin/setserial and removing 
/dev/ttyS0 and /dev/ttyS1.

That would exclude all possible uses of the codepath affected by that 
commit, right?

If yes i'd shuffle this into the 'weird things' bucket, waiting for a 
more debuggable scenario to pop up.
