      I’m seeing significant waits on userlocks on the active hciengine process on 5.6.  I’m seeing significicantly greater than 50% time spent in userlocks (observed in the LCK column when running prstat -am.  On 5.2, I see consistently less than 50 % time spent waiting for userlocks.

      Any ideas?  this is in solaris 10 running on a 1.2 GHz T5220 with 64 threads (8 cores) and 32 GB or RAM.  No other system resource seems stessed at all.

      Anyone running 5.6 on Solaris 10 on T2000/T5220, or similar CMT boxes?

      Mike
