Ok, I let the IPMI sit, and it eventually showed me the console.

I took a screenshot, and then reset the box.  I did get a textdump
but it didn't run my scripts for the ddb stuff.

Here is links to what I do have:

$ ls -l
total 5017
-rw-r--r--  1 ler  ler  5051465 May 29 13:14 crash.stats.tar.gz
-rw-r--r--  1 ler  ler      253 May 29 13:18 index.html
-rw-r--r--  1 ler  ler    77004 May 29 13:16 ipmiconsole.png
-rw-r--r--  1 ler  ler    70656 May 29 13:14 textdump.tar.6

What else can I supply?

The crash.stats.tar.gz contains the minute by minute output of the followuing
script for the entire boot:
DATE=`date +%Y%m%d.%H%M%S`
(echo "Uptime:";uptime;echo "vmstat -m:";vmstat -m
  echo "vmstat -z:";vmstat -z) >/home/ler/stats/${DATE}.stats
