Ryan, I believe the large file aspect of the bug is an incorrect characterization. If you take a look at comment #184, you will see that I have reproduced the bug on much smaller files.
-- in-place corruption of large files *without fsck or reboot* reported with linux 2.6.31-14.46 on ext4 https://bugs.launchpad.net/bugs/453579 You received this bug notification because you are a member of Mythbuntu Bug Team, which is a direct subscriber. Status in The Linux Kernel: New Status in Ubuntu Release Notes: Fix Released Status in “linux” package in Ubuntu: Triaged Status in “linux” source package in Karmic: Triaged Bug description: There are worrying reports of filesystem corruption on ext4 in karmic. Scott says: 12:36 < Keybuk> this whole ext4 thing is worrying me 12:36 < Keybuk> I just downloaded an iso image, md5sum didn't match 12:36 < Keybuk> downloaded it into an ext3 partition, matched just fine 12:59 < Keybuk> and I know mvo has seen bugs with corrupted .debs in /var/cache/apt/archives 12:59 < Keybuk> which seems to imply its any file large enough to use lots of extents I'm opening this bug report so that this bug gets tracked & triaged for karmic. If we're unable to isolate the issue, we should consider rolling back to ext3 as the default filesystem in the installer.
