What version of e2fsprogs is (the other) Andreas' tree based on?  The
newer e2fsprogs-1.43 has support for metadata checksums, but this should
be off by default in the released version.  The testing version had it
enabled by default.

With the working e2fsprogs, you could run:

 dumpe2fs -h /dev/sdb1 | grep -i feature

and see what features are enabled (in particular metadata_csum, and maybe
if the RichACL has its own feature flag)?

Cheers, Andreas
