Personally, I'm not very proficient in d-i (read: not at all), so I'm
getting -boot into the loop forwarding your request, for help. Bottom
line for d-i, to test the patch proposed to fix #512740, we need a d-i
sparc image to check for regression on sparc. The patch is attached for
your convenience, see bug log for full context.
Thanks for your feedback!
Cheers.
