got the same messages on my t5120 with kernel 4.6.1 :

Jun 09 15:48:24 nvg5120 kernel: io scheduler cfq registered (default)
Jun 09 15:48:24 nvg5120 kernel: Kernel unaligned access at TPC[73b92c]

Jun 09 15:48:24 nvg5120 kernel: f0286d78: ttyS0 at I/O 0x0 (irq = 17,
base_baud = 115200) is a SUN4V HCONS

but 4.7.0-rc2+ (from git), does not have it, probably fixed.
