yes, the last time was with bad memory.
Try (== adapt) this script:
#!/bin/sh
VERSION=linux-2.1.127
FILE=/share/archives/linux/kernel/v2.1/$VERSION.tar.bz2
DIR=/usr/tmp/tt_$$
mkdir -p $DIR
chmod 700 $DIR
cd $DIR
bzip2 -d < $FILE | tar xf -
mv $VERSION linux.save
while :
do
bzip2 -d < $FILE | tar xf -
diff -U 3 -rN linux.save $VERSION
if [ $? != 0 ]; then
echo "ABORTING, data still there"
exit 2
fi
sleep 30
rm -rf $VERSION
done
cd ..
rm -rf $DIR
# If that script spews anything to the screen, you've failed your memory
# test. The only exception to this is if your disk sub-system doesn't use
# DMA, then this test is not as good as it could be, but if your system uses
# DMA (such as a decent SCSI controller, or DMA IDE) then this test will show
# bad RAM much faster and more reliably than compiling a kernel.
