Description 
When ufs file system with logging enabled is created on zvol, this might cause system hang due to deadlock.
Work Around 
Disable ufs logging.
increase buffer cache highwatermark, bufhwm

do not run UFS on zvol's
Increasing the UFS log size on the affected filesystem may make the problem less likely, by setting ldl_maxlogsize to 0x10000000  (256Mb) in /etc/system
