(happens with ext3 also) :( I think I may have missed a fix for ext3 ordered and journalled too (I've just sent a patch to Andrew privately). Sorry. Can you try with ext2? Alternatively, try with ext3 or reiserfs and change the line in mm/filemap.c:generic_file_buffered_write from status = a_ops->commit_write(file, page, offset, offset+copied); to status = a_ops->commit_write(file, page, offset, offset+bytes); and see if that solves your problem (that will result in rubbish being temporarily visible, but there is a similar problem upstream anyway, so it shouldn't cause other failures in your test).
