This is panic crash. does the crash create crash dump? (Assuming that you have configured crash)
If yes look at /var/adm/crash dir.
Look at /var/tombstones/ts99 file.

Also, if system has generated crash, post the outout of following.

cd /var/adm/crash
adb /var/adm/crash/crash_dir/vmunix -m /var/adm/crash/crash_dir

Once on adb prompt, do "msgbuf+8/s

What does stack trace say??
Also does ts99 file denotes HPMC errors??
