Some SPARC systems require a firmware update in order to boot Oracle Solaris 11.2. On systems that have not been updated, the following error message might be displayed when the system is booted:
os-io Cross trap sync timeout:
Workaround: Update your affected system's firmware to the version listed in Table 1–3 before you install the Oracle Solaris 11.2 OS. The following table describes the minimum firmware level required for affected SPARC systems when running Oracle Solaris 11.2.
Note that T4, T5, M5, and M6 systems were released with firmware versions to boot Oracle Solaris 11.2. However, the firmware needs to be updated if Oracle Solaris Kernel Zones support is required. For information about hardware and software requirements for kernel zones, see Hardware and Software Requirements for Oracle Solaris Kernel Zones in Creating and Using Oracle Solaris Kernel Zones.
