I'll send you the image off-list. Yes, I expanded a tar to the disk when triggering the hard reboot (without shutdown). This seems to increase the rate of failure. But also normal shutdown might cause similar problems, when the acpi powerdown is done quickly, perhaps before all caches were written to disk successfully. I have had two occurrences where a normal shutdown of a system with disk encryption caused data corruption in dpkg state list, which were not modified during that session. Probably the last modifications of syslog et al. before unmounts did not make it to the disk cleanly. By the way, since this can be reproduced at least on Ubuntu lucid, I filed a bugreport there to have a first identifier: https://bugs.launchpad.net/ubuntu/+source/jfsutils/+bug/754495 Roman ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
