Doesn't help at all, so that problem does not seem to be related to features:

# zpool create -o feature@extensible_dataset=disabled -o 
feature@userobj_accounting=disabled -o feature@project_quota=disabled -o 
feature@log_spacemap=disabled -o feature@allocation_classes=disabled -o 
feature@large_dnode=disabled -o feature@encryption=disabled -o 
feature@spacemap_v2=disabled -o feature@bookmark_v2=disabled -o 
feature@obsolete_counts=disabled -o feature@zpool_checkpoint=disabled -o 
feature@async_destroy=disabled -o feature@empty_bpobj=disabled -o 
feature@lz4_compress=disabled test /tmp/pool

# cat /home/lsdf/SAT/Processor/Results/imk/32@20100825 | zfs receive -d test
cannot receive new filesystem stream: invalid backup stream
