Indeed you said that, but that's about as content-free a problem
report as I've run into.  What are the regression diffs?  (If
they're massive, the first few would still be useful.)  Does it
get hung up entirely?  Are there crashes, and if so can you get
stack traces from them?  You really shouldn't expect people to
spin up an environment like this just to see what happens.

Interesting, but again, how about a stack trace?
