The Solaris version reported in the copyright banner on the ISO is SunOS
Release 5.11 Version 11.4.0.15.0 64-bit

My existing guest solaris systems are also at the same release/version level

At the time of the panic, the panic log reports that the rcx register
contains '0606' (this was from my notes yesterday).  If additional
information is needed, I will need a bit more time to set up my system
again.
