My test case is Debian's "aptitude update" running once an hour, and it was always the same file getting corrupted. With 2.6.19, I had this corruption like every third hour (but -only- if run from cron, running from a shell was always fine), data=writeback made the issue disappear for about two days before I booted into 2.6.19.1 without data=writeback (defaults chosen then), after which the issue only shows up like every other day. So, I feel like out of the loop since rtorrent seems much better in reproducing this. I notice, though, that both aptitude and rtorrent do downloads from the net, so there might be a relation to tcp/ip and/or the network driver. My box has a Linksys NC100 network card running with the tulip driver.
