Unigine Heaven has allocation requests for example required pages are 161 and alignment request is 128. To allocate the left over 33 pages, continues the iteration to find the order value which is 5 and 0 and when it compares with min_order = 7, triggers the BUG_ON((order < min_order). To avoid this problem, round_up the size to the alignment and enable the is_contiguous variable and the block trimmed to the original size.
