How many people besides you can reproduce this corruption on definitely reliable
hardware? After my first report I have been unable to reproduce it at all, which
means that the damage could have happened on any one of many previous proper
unmounts, under a variety of kernels.

I have seen this on my own system with definitively reliable
hardware--over 60 days uptime, then I had to shut it down to take it
home from the dorm (all I need is a bigger UPS battery :-) When it
does a time- or reboot-forced fsck (with the HDDs marked as clean), it
always finds one or more deleted inodes with dtime set to 0. I had
always ignored it, though.

FYI--Hardware info:
