[Bug 453579] Re: in-place corruption of large files *without fsck or reboot* reported with linux 2.6.31-14.46 on ext4

[Nicky Gillette]

The different checksums affects me too, I'm using the final release
version of 9.10 on an Intel Celeron on a laptop.

I did RAM tests with a live copy of 8.04, for many hours with no errors, so I don't think it's bad memory.
8.04 works (with default ext3), 8.04 alt w/ full disk encryption works, also with normal checksums.

9.10 gives errors (with default ext4), w/ home directory encryption, I
also get bad checksums.

9.10 live CD also gives me errors when I haven't even installed it when I use:
sudo shred -xvfz -n0 /dev/sdb      # A USB flash disk I wanted to wipe

It failed at 4.7GB and started saying something about sync errors.

This same file operation works fine with the 8.04 Live CD.

I wonder if it's not just an ext4 problem, but a problem in the way 9.10
handles large files.
