Comment 39 for bug 317781

Same data loss problem.

Installed Kubuntu Jaunty Alpha 4. ext4 as root / partition. Did all the updates.

$ uname -a
Linux andor 2.6.28-8-generic #26-Ubuntu SMP Wed Feb 25 04:28:54 UTC 2009 i686 GNU/Linux

ran the "write_stuff" script, and held down the power button after about 5-10 seconds.

I'm happy to try other tests that people may suggest.
