Hmm, I'm not aware of any mm->mmap_sem starvation issues in 3.18-rc, maybe 
this is a duplicate of another issue that someone has reported that I 
haven't seen.  The lengthy output of echo t > /proc/sysrq-trigger should 
give a clue as to what is holding it or perhaps this is a more generic 
rwsem issue.
