Hmm, thats odd. It seems to be coming from:
reiserfs_commit_page -> reiserfs_add_ordered_list -> __add_jh(inline)
I guess XFS may have left a buffer_head in an unusual state (with some
private flag/b_private set), somehow, and perhaps that buffer_head has
later been allocated for a page in a reiserfs write. Does this patch,
below, help at all?
I see one BUG check in __add_jh for non-NULL b_private, but can't see
the top of your console output from the photos - is there a preceding
line with "kernel BUG at ..." in it?
cheers.
