Interesting; I posted a similar bug report on 2016-04-19 titles
 [BUG 4.1.11] EXT4-fs error: ext4_xattr_block_get:299 - Remounting
filesystem read-only

I never got a reply.

That one happened on 4.1.11 on a virtual machine running inside
VMware-ESX after a hardware change. Last change was to disabled the
pvscsi drivers again; the system seems to be running fine since 1 week,
but the first time it took 1 month to notice the corruption, so we're
not yet sure that the problem is solved.
