I'd just like to chime in real quick... I've written a short bash script
that has proven to be pretty good at crashing my SMP/SCI boxes on 2.6,
it seems that UP/IDE systems are OK but I'm not sure which part of that
equation makes the difference.  It is just a little script that copies
the portage tree around and tars/untars it.  On my boxes, it always dies
on copying /usr/portage over (seperate disks) and I don't think I've
ever made it to 10 iterations.

Anyone who has time/ability please run this script and send me the
results and I'll tally them up, maybe someone can even get an OOPS.


Here is the script. I always clear out /usr/portage/distfiles before I
run it.

mkdir /var/tmp/crash
cd /var/tmp/crash
while [ 1 ]
~        echo -n "Copying /usr/portage to /var/tmp/crash "
~        date
~        mkdir portage
~        cp -R /usr/portage/* portage/
~        echo -n "Create tarfile "
~        date
~        tar cf portage.tar portage
~        echo -n "Removin portage "
~        date
~        rm -r portage
~        echo -n "Untar "
~        date
~        tar xf portage.tar
~        echo -n  "Removing portage "
~        date
~        rm -r portage
~        let X=$X+1
~        echo -n "Run ${X} completed "
~        date
