Chiming in here with a carefully qualified "me too".  

I have an M1015 crossflashed to 9211 IT firmware, (without an expander, but
using adapters to break out to a separate jbod), and during heavy IO I'm seeing
errors on write commands of similar nature as this:
length 131072 SMID 79 terminated ioc 804b scsi 0 state c xfer 0.  

These drives are 2TB RE4's.  

I was initially at P17 but tried updating to P19 to see if it'd make a
difference with this issue (it hasn't).  While it hasn't seemed to cause any
failures, it is a bit worrisome.  I hadn't seen any such issue with reads (such
as with a weekly scheduled scrub).  

Only seem to see the issue on the IBM branded controller, others are true
9211's flashed to P17 IT firmware.  However, other drives mainly consist of WD
blacks.  Half tempted to buy or swap controllers around to see if I can find
the consistency but I'm a little bit afraid to roll the dice with my data like
that.
