It looks like there is a problem dumping a kernel panic on an X4500. During the self induced panic, there where additional syslog messages that indicate a problem writing to the two disks that make up /dev/md/dsk/d2 in my case. It is as if the SATA controllers are being reset during the crash dump.
At any rate I will send this all to Sun support. Thanks.
