Does this mean that each system spent about 400 minutes on these?

This only tells us that some problem is still present at least on "zed"
with the new bitstream.

I suggest that you use a smaller wordlist and a smaller list of hashes -
e.g., 64 of each (with every word actually cracking a password) - and do
many more invocations.  This will likely trigger the problem more
frequently (because more of the bcrypt computation results will actually
need to match a loaded hash).  Maybe you'll trigger it on the "embecosm"
system too.
