Apparently bbolt is a fork of boltdb, so please see my comments
on the equivalent bug report againt boltdb:
https://bugs.debian.org/976907


Relevant part:
 It seems the test-suite makes assumptions related to calculations that
 involve os.Getpagesize() (which gives 4096 on amd64 and 65536 on
 ppc64el, which is 16 times larger).
 Changing the 500 number to 8000 (16 times larger) in
 TestBucket_Stats(...) (in bucket_test.go:1143) gives the expected
 BranchPageN == 1 .... (however after that it then says 
 "unexpected LeafPageN: 6" with this modification).

 In my opinion it's pretty clear that these are test-suite only
 issues and not issues in the actual product.


I would thus personally just disable the test-suite on !amd64 if no
porter is interested in fixing the testsuite (unless we agree this
issue simply can be downgraded to non-RC).
