The system might panic due to "BAD TRAP" during boots after the upgrade from Solaris 11.0 to 11.1 and Solaris Cluster 4.0 to 4.1.
The panics are intermittent even on the same machine and might not occur all times you reboot after upgrade.
The stack trace reported in the message files after the panic message shall report the following function names:
Solaris Cluster 4.0 (including SRUs) is not subject to this problem. The key change leading to the panic is the upgrade of Solaris Cluster to 4.1 series and in particular to SC4.1 or SC4.1 SRU 1 to SRU 5.
The command "pkg update" do normally update all installed software installed including both Solaris and Solaris Cluster, therefore any unconditional update might trigger the issue unless the pkg publisher for Solaris Cluster do refer to SRUs which contain the fix.
