There are a number of patches committed to upstream in the last couple of days that might fix your problem. See:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/
and look for:
pipe: Fix iteration end check in fuse_dev_splice_write() pipe: fix incorrect caching of pipe state over pipe_wait() pipe: Fix missing mask update after pipe_wait() pipe: Remove assertion from pipe_poll()
