That's about the bug I mentioned at the end of my mail, the exact paragraph you cut out when quoting me. :) Someone suggested the dubious Ubuntu report was a case of the verified upstream bug, but it doesn't look like that to me. The upstream report is about corruption of _any_ size files _on a dirty shutdown of the system_. The Ubuntu report is about corruption of only _large_ files, with no need for any kind of shutdown and reboot before the problem is observed. They look like different issues. Personally, as I said, I don't much credit the Ubuntu report, at least unless some other people independently confirm the same problem. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
