The former is the version that shipped with 12.0; it's *not* the same
as the latter, which is symlinked as 'current'. The former has the
following sha1sum: 8b8a7e8b1fc127e8704a63e54a93e84b985ccd4a and does
exhibit the problem you're mentioning (and it's normal for older images
to behave that way).
All images I download are sha1sum c29dca30d20cbc0deadc6eec22e8ff3c2e9c0bf4....
To be sure we're talking about the same thing, can you post the actual URL of the image with sha1sum 8b8a7e8b1fc127e8704a63e54a93e84b985ccd4a?
thx
