I've been away on vacation so I haven't been able to try your latest patch, but I can try whatever is out there starting this weekend. I was getting fairly consistent hangs during heavy IO (especially rsync) on 3.15 with lzo enabled. This is on raid1 across 5 drives, directly against the partitions themselves (no dmcrypt, mdadm, lvm, etc). I disabled lzo and haven't had problems since. I'm now running on mainline without issue, but I think I did see the hang on mainline when I tried enabling lzo again briefly.
