I am experiencing a similar hang when updating from r246190 to r247017 on my all zfs system. The system has two drives in a zfs mirror and hangs after detecting the hard drives. The last thing seen is the "ada1: Previously was known as ad8" message, then it hangs completely, unable to even ctrl-alt-del or even get the numlock key to toggle the light. System is: CPU: AMD Phenom(tm) II X4 955 Processor (3214.39-MHz K8-class CPU) with ASUS M4A78LT-M board. Let me know if other details will help. Steve
