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.
