What's the bug number? (Never mention bugs without the bug number).

Why choose that bug to look at in the first place? You have to choose a
bug that you have some chance of fixing.

There are lots of bugs that are easier to fix than this one.

One machine for each supported architecture is available to DD's but
only via remote SSH access.

By careful requests for specific information from the person who does
have such hardware and by a thorough knowledge of the codebase to work
out if something that is not directly hardware-specific is actually the
problem but is just being "hidden" on more common hardware. e.g. this
could be a race condition but as you didn't provide the bug number,
no-one can help with that specific problem.
