Found this bug after appling the patch 141414-10 on a T5220. It is a standard practice to apply the JASS toolkit on the system. By default JASS restrict /tmp to 512mb. This can cause problems on sun4v machines, because bootadm will fail to create the boot_archive, making the server unbootable.
To recover this problem you can check my post about recover Solaris under SVM.
