help needed for fixing zfs bug

Hi Experts

I've problem in a my office server (solaris 10 - x86) version. x4600 M2 hardware

This system is getting rebooted because of zfs bug

I've applied patch using live upgrade with live new environment created and
applied the patch which oracle suggested(
144501-19), it asks for dependenices, we installed all the dependenices

still the we get this message when try luactivate new environment

ERROR: Unable to determine the configuration of the current boot environment

Also we deleted the new enviroment

Also We tried to luactivate current, the same error occurs

could anyone of you have any idea on this or procedure which will help to fix this issue. Any help is much appreciated
