Description

I'm running latest SmartOS (20150108T111855Z) and I've encountered this crash (the full information is attached):

Using the same pool with the same LZ4 dataset didn't crash the system before this release, but the Illumos/SmartOS changelog do not show any changes in ZFS/LZ4 area in the past month (the other two SmartOS releases).
