Ok, I've able to reproduce corruption on ext4
So at this moment we have:
Slub corruption on XFS testcase: xfstests/generic/013
Slub corruption on EXT4 testcase: xfstests/generic/299

In fact both test cases (069'th and 299'th) are just stress tests.
So this is likely a regression in mm layer. I try to bisect it now.
