So what about data corruption?
Did you encounter it after enabling swap?

Edward.
This happens without any memory pressure, with 4G of 8G RAM free and
no swap activity.
I reproduced it on freshly booted system.

That was it, no more BUG on mount.
I spoke prematurely.
Looks like I had 2 different BUGs on mount:
1. BUG when mounting partition with old disk format - that was
solved
with 4.8.1 patch
2. BUG when mounting dismounted partition - this one is not solved
When I I get this BUG I do:
echo 1 > /proc/sys/vm/drop_caches
and everything works OK again.
With echo 1 > /proc/sys/vm/drop_caches added before mount to scripts
that I run daily on R4 partitions I had no occurence of this bug and
before I had it every day.
When partitions are mounted on boot they mount OK, but when system
finishes booting when I try to mount them I get this BUG:
