kernel panics from list corruption when using a tape drive connected through cciss adapter

Issue

• c program which reads and writes to tape drive from buffer caused kernel panic. Same c program is tested on other controllers on RHEL 5 and it does not cause a panic.
  Suspecting problem could be with kernel/cciss driver/P212 controller.

#!/bin/bash
LOGFILE=/tmp/tape.`date +%Y-%m-%d-%H-%M-%S`
echo "Starting Test" >> $LOGFILE
i=1
while [ $i -lt 100 ] ; do
       echo -e "---$i---\n" >> $LOGFILE
       /rfu/rfubin/rwtape -b 65536 -n 65536 -i 2>> $LOGFILE
       let i=i+1
       echo -e "------\n" >> $LOGFILE
done
echo "End Test" >>  $LOGFILE

Kernel panics are intermittent, on various iterations.
