I am seeing this BUG on 3 different sparc64 machines with yesterdays git. sparc64-specific known problems were just fixed before, 3.17.0-07551-g052db7e + slab alignment fix patch + sparc64 SIGBUS fix patch is working stable for me, whereas 3.17.0-09670-g0429fbc + SIGBUS patch fails on 3 machines (all I tried). Will try bisecting later if I get time.
