A quick test with a 5.9 snapshot show the same behavior. I'm not familiar with the kernel sources, but a quick gdb session reveal that there is a problem with the mpath selection. I look like the dest address used to compute the hash is always empty, so the hash end's up being always the same value. I will fill a reports with the information I managed to gather. Thanks.
